关于一个建筑和技能的作用......

游戏中有个建筑“Seal of Hermaton”，我把它译作“荷马顿封印”。它的作用是“Gives +1 charge per turn to the occupying player. Occasionally spawns units to defend itself.”其中这个“charge”具体是指什么东西？

还有半身人族有个技能“Nourishing Meal”（营养午餐）。原文是“Increases maximum hitpoints of unit by {nourishingmealHeal} and gives {nourishingmealMoraleBonus} to target friendly unit. Outside combat any units in the stack are healed for a maximum of {nourishingmealHeal} divided by the number of wounded units in the stack.[br/][br/]Undead units can be healed with this ability, but are unaffected by the morale bonus. Incorporeal and Machine units can never be affected.”一直没弄明白该技能回复已受伤单位的生命是如何计算的。比如现有两个受伤兵的生命值是30/40和40/50，那对他们施放该技能后数值该如何变化呢？请知道的人能说一下。
