Arcane Fire (Su): The archmage gains the ability to change arcane spell energy into arcane fire, manifesting it as a bolt of raw magical energy. The bolt is a ranged touch attack with long range (400 feet + 40 feet/level of archmage) that deals 1d6 points of damage per class level of the archmage plus 1d6 points of damage per level of the spell used to create the effect. This ability costs one 9th-level spell slot.
At the cost of psionic focus or a fair bit of damage depending on the power's level. And also note that the sorceror can use metamagic rods to empower, maximize, or quicken her highest level damage spells (provided she has invested in such rods), which is often significantly better than mere overchanneling.Then there is Spell Power, a good ability, since it let's you scale spells even further (caps are still a hindrance, however), but compare this to Overchannel/Talented, which the psion can exceed the power level of their powers with (not only the manifester level).
Scion said:Grapple = bad for all 1/2 BAB classes. If they dont have a way around grappling then they are dead, either way.
Psion is slightly better off, but dead is still dead.
Elder-Basilisk said:Not really.
Scion said:(anyone know if grappling damage counts as continual or not?).
I have said from the beginning that the psion is better off, but any caster caught in such a situation without some sort of plan is in for a world of hurt.
