大佬们，关于创伤之书的预置仪式，萌新有几点不太懂

[psp991]

rt，最近在玩魔战士，看指南里推荐魔法物品有这个创伤之书，对它的预置仪式有点疑问
“创伤之浪（Harmful Surge）(Su)：你可以将法术发挥至极限，但是这么做同样会伤害到你。当你施放法师的塑能法术时可以以自由动作消耗该增益效果。当你这么做时，可以视同使用法术极效超魔专长（Maximize Spell metamagic feat）施放该法术一般，但是你会受到1d4 x 你要极效超魔的法术等级点伤害。由此受到的伤害无法以任何方式减免。”
主要疑问是1：他说“释放法师的塑能法术时”，这里是指施展的法术要是法师放的，还是在法师表里有就行呀，比如我一个魔战放电爪能触发这个效果吗
2：他说视作使用法术极效超魔专长施放该法术一般，还是以电爪为例，我用1环准备电爪，然后释放这个1环电爪，再自由动作释放这个创伤之浪，那我这个电爪还是1环吗，还是需要按超魔规则升环，改为消耗4环

Book of Harms (Spellbook, Level 5 Evoker)
Source Ultimate Magic pg. 122
The leather wrapping of this book is of an indeterminate type, and gives off a faint and unpleasant scent, as of charred meat. The writing inside is in a jagged hand, and many notes on the ash-smudged pages indicate its previous owner sought ever more damaging magic. A glittering rune in the cover’s center is shaped vaguely like a lightning bolt.
Opposition Divination, transmutation
Protection Average lock (DC 25)
Value 535 gp (900 gp with the preparation ritual)
Spells
3rd—fireballS, lightning boltS
2nd—acid arrow, darknessS, ghoul touch, gust of windS
1st—burning handsS, color spray, corrosive touch, hydraulic pushS, hypnotism, magic missileS, ray of enfeeblement, shocking graspS
Ritual
Harmful Surge (Su) You can maximize a spell, but doing so damages you. Spend this boon effect as a free action when you cast a wizard evocation spell. When you do, you can treat that spell as if it were cast with the Maximize Spell metamagic feat, but you take 1d4 points of damage × the level of the spell that you are maximizing. The damage you take cannot be reduced in any way.

1：男神站原文中说的是wizard evocation spell，没有任何其他前置要求（例如“你是个法师”），所以可以认为他的要求是施展在【法师法表】里的【塑能系】法术
2：法术超魔的环位提升仅在每日准备/决定自发施法的那一刻决定，【创伤之书】则是在你决定施法后~法术起效前这个时间段临时插个【法术极效】超魔，不会提升法术环级
