This will serve as a basic review of what hero aides are, along with my recommendations for how to use them, and a rating for each one.
Types of Heroes: If you clearly define your heroes role, you can choose aides and prioritize them
Before that though, I will categorize each hero into their main roles:
Attackers, their main role is to do damage: Berserker, Demon Slayer, Chiron, Djinni, Ambrosia, Abyss Demon, Sapphirix, Wonton, Arcane Caster//Recommended Aides: Sapphirix, Chiron, Blockhead, Hydrasaur, Skull Mage, Djinni, Abyss Demon, Arcane Caster
Hybrid, they can do some very nice damage, but their rage skills and divine going off are more important than how much damage they do, often for crowd control purposes: Carol D, Great Sage, Dark Rider, Pan Goli, Arctic Lord//Recommended Aides: Sapphirix, Hydrasaur, Chiron/Berserker(for GS mainly), Arctic Lord, Enchantress, Savage Chief, Landslide, Wonton, Toxic Shaman
Support, they aren’t meant to do damage but rather stay alive to use their skills: Renee Ven, Enchantress, Toxic Shaman// Recommended Aides: Savage Chief, Hydrasaur, Enchantress, Arctic Lord, Landslide, Berserker, (extra Sapphirix perhaps?), Wonton, Toxic Shaman
Tank, they are meant to receive damage and stay alive: Savage Chief, Pounder, Landslide//Recommended Aides: Savage Chief, Arctic Lord, Enchantress, Chiron, Berserker, Landslide, Ambrosia, Wonton, Toxic Shaman
Troop Based, their main damage will be done through their mercenaries: Skull Mage, Glory Priestess, Blockhead, (sometimes: Chiron, Sapphirix)//Recommended Aides: Demon Slayer (for all), Shining Wizard (for Wiz types), Renee Ven (for Sharpshooters), Pyro Pete (for Sharpshooters), Blitz Bomber (for all), Carol D (for all)
Pan Goli- 10/10. Perhaps the best hero aide as opponents need to design speicific strategies to combat against it and having the extra time to fire off a healing skill or one last attack is just too good. It’s amazing for all game modes and you will almost always be using one except possibly a Great Sage on Defense and certain BR situations.
Sapphirix- 9/10. 25% HP & 25% DMG. My rating: 9/10. While the 25% HP is nice, the 25% DMG is where he truly shines. I mentioned how ATK is added on to your heroes (meaning it is a percentage based off of the raw unboosted attack). However, the Damage multiplier goes on at the end of the formula. Meaning it’s total calculated ATK (with raw, +, and +%)*DMG multiplier. This multiplier makes it much more potent than even a 50% ATK boost from SM because the damage from weapons, enchants, and evo gets multiplied by your damage multiplier. Best used: Attackers, Hybrid.
Toxic Shaman- 9/10. 30% DMG Reflect; releases poison cloud upon dying (7K DMG/sec + 10k Heal/sec + reduce ATK Rate & Speed for those in cloud). He is a super sweet hero aide for heroes that die multiple times (or in Hero Trials- hint: give to your hero(es) who die first!). Great Sage is a sweet choice on defense and a second choice could be Enchantress. Best used: Hybrid, Support, Tanks.
Enchantress- 9/10. At higher levels she is annoying! Very good for keeping heroes alive longer. This is particularly evil paired with an LS on defense, or Enchant on Defense 🙂 Best used: Hybrid (think Great Sage), Support, Tanks.
Blockhead- 9/10. He is a very (very) nice hero aide, giving 50% increased attack speed. This is an excellent boost for hard hitters and a fun aide to add to heroes who have other procs on their attack (i.e. the Thunder Blade, Bow, Abyss Demon Aide). Mathematically, a 50% attack rate will increase total damage output more than any other single hero aide. Best used: heroes with blades or bows (Abyss Demon/Ambrosia or anyone else who hits fast already).
Arctic Lord- 8/10. The damage reduction is huge when starting battles and devastating when enemies try to damage your base (or kill your reswpawning great sage). Or even in Hero Trials this is activated every time a new hero spawns. Best used: Tanks, Great Sage (support on defense can work too).
Chiron- 8/10. 40% ATK & Damage & Skill Damage/DMG Reflect. The best use of Chiron aides is his damage and skill damage reflect. Therefore, the best use of him would be when enemies focus on your target. Best used: (if all your heroes have one) or really Landslide (who can force heroes to attack him). The best and my favorite use is Great Sage on Defense. He can often be the last remaining hero and thus it is very common to have everyone focusing on him. Damage reflect plus his skill/divine can be devastating.
Djinni- 8/10. Has the potential to be a monster aide, especially with Legendary Equipment. And the extra 30 fury is amazing for Arcane Tome users. Also, for example, a +2 orange blade I have gives 17% extra CRIT, but no CRIT Damage. Adding a CRIT Damage modifier increases its output significantly. Best used: Attackers, Tome users.
Berserker- 8/10 (The Guild Boss Destroyer Aide). Could be very nice, especially to prevent lower health support like Renee Ven from being one shot by beefy enemy Great Sages or Berserkers or now, and perhaps most important, Wontons!! My Wonton is hitting for 200k+ with his Divine 2. That hurts, especially when he’s on defense! Sometimes a Savage Chief HP boost doesn’t cut it, but Berserker can do the trick. Best used: Tanks, Support, Great Sage (even attacks vs. Guild boss).
Wonton- 8/10. 30% dodge from Orange Heart, 15% dodge from 3x talents, 17% dodge from Wonton aide, 15-20% dodge from enchanting = ninja mode!!! 75-80% dodge rate plus the extra 25-30% from when they actually hit you enough to get your Heart to proc. Best used: Tanks, Support, Hybrid.
Landslide- 7/10. Perhaps an underestimated hero aide. Over 30 seconds he will heal you for 21% of your overall health. If your health is already quite high, 21% health on say 400k is quite significant. Best used: Tanks, Support.
Arcane Caster- 7/10 (10/10 for certain situations). She gives an outstanding Damage buff if you have more heroes than the enemy. This ought to work in the guild boss mode and is super powerful for finishing off enemy bases or attacking enemies. I think at max level it gives up to a 48% DMG boost, 2x the benefit of Sapphirix! Best used: Attackers.
Hydrasaur- 7/10. 36% ATK and 36% HP. A nice combination hero that helps you stay alive. My rating: 8/10. Best used: Hybrid, Attackers, Support (if you build the frontlines well you can boost support dps).
Savage Chief- 7/10. He is a good aide, giving a boost of up to 50% HP (note this boost is not 50% of what you see, but 50% of their base HP stat excluding weapons, evolution, and other boosts). His effectiveness is less now with hero equipment and hero enchanting but he is still good. Best used: Support and Tanks.
Skull Mage- 7/10. He is a fine hero aide because of a 50% ATK boost (though this is also based upon a hero’s base stats and excludes weapons, enchants, and evolution before it is calculated). Was better before hero enchants and weapons. Best used: Attackers.
Abyss Demon- 7/10. AOE attack every xx attacks. Best used: Attackers/ pairing with blockhead aide or with Thunder Blades for extra AOE.
Ambrosia- 5/10. I have never gotten excited about using her to boost healing. Best used: Tanks or ranged heroes (as when they die, their skeleton becomes a range hero and can last longer than melee).
Renee Ven- 10/10 (for Sharpshooter build in BR), 5/10 elsewhere. Amazing for Sharpshooter build in Battle Royale, okay to buff sharpshooter mercs elsewhere.
Demon Slayer- 10/10 (for mercenary builds), 1/10 otherwise. Amazing when your main damage is done by mercenaries (like a Sharpshooter or Wizard build). Or… he is very nice for giving Arcane Tome users with Wizards up to 20 extra fury. This means you can start with 80 fury to begin a battle (with Djinni, Demon Slayer, and 15 wizard mercs). For fun you could get the merc# boosting talents, but at that point I prefer more killing power 🙂
Great Sage- 4/10. Spawns monkeys. These monkeys at best can really just soak up some hits that otherwise would have gone to your main heroes. Best used: Flying heroes. Funnily enough, this can slow down melee attackers who keep doubling back for a flying hero dropping monkeys on the ground.
Dark Rider- 1/10. Flat ATK up boost. Perhaps one of the weakest aides. Down there with Glory Priestess. He is a nice hero himself though, and could be even more fun with blockhead’s evolution. My rating: 1/10. Best used: when you have nobody else.
Air Elite- 1/10. Currently a waste of everyone’s time. Her HP bonus scales linearly which gets overshadowed by weapons and hero enchants. My rating: 1/10. Main purpose: Currently only as an IGG troll. May have some use if her divine can boost damage by flying units.
I won’t discuss other mercenary buffing aides: Carol D, Blitz B, etc.
