I hope that Thom's explanation answers your questions.
Txs to both.
I've been chewing the answers and I think I've got it.
Actions "happening simultaneously" has been somewhat difficult to insert in my RM rpg mind.
I must say that melee combat breaks that rule between the engaged parties. As who wins init may choose to hit first (he can full parry!!) and affect his foe before he/she/it swings back. I think if both have the same init, blows will be simultaneous too.
So, an example to end my doubts:
a) The mage vs archer got it right. Both will act. The init factor afects the Mage, so he could cast a normal AND instant (has win init) or only the normal OR the instantaneous (has lost init). (More an statement than a question)
b) Instantaneous like Bladeturn. A spellcaster can cast a Bladeturn against a target regardless his init value, and will take effect once (if in this round) this target attacks, even if target has the highest init. Meaning Bladeturn will always affect a melee (whatever init has the spellcaster) since it is “instantaneousâ€.
c) One round casting like Jolts. The spellcaster declares jolts against a target wich is in melee against his friend ranger.
c1) The mage wins init vs the foe. So the Jolts is cast and affects the target. If it gets stunned his friend ranger can attack against this “stunned†foe at will.
c2) The spellcaster loses init against the foe. Normally, the foe will swing against the ranger before the spellcaster casts Jolts. (Very important stright answer here, please) So if Jolts affects him, he will be stuned for next round, since this one has already acted attacking the ranger.
c3) But the spellcaster, can interrupt his Jolts and cast Bladeturn instead, that takes effect before the foe swings and thus affects his attack against the ranger, right? Even if the caster had the lowest init.
I hope this will be the last post because of this doubt, hope so
, since I think all answers must be simply ...... Yea !!!
