I have seen this EXACT post relatively recently.
Apothecary can crit heal, he needs to be as close to 100% crit rate as possible. He heals 35% of the targets MAX HP or 52.5% of their MAX HP when it crits, unbooked.
Soothing Chant (Cooldown: 3 turns)
Heals a target ally by 35% HP. This Heal can be critical.
Level 2: Heal +5%
Level 3: Heal +5%
Level 4: Heal +5%
Level 5: Cooldown -1
Healing Multiplier: 35% HP (Non-Critical), 52.5% HP (Critical)
-----------------------
Each skill level up (+5% Heal) is counted as multiplicative NOT additive.
Apothecary’s total heal skill is not 35% + 15% = 50% but 35% x 115% = 40.25% for non-critical, and 52.5% x 115% = 60.375% for critical.
