arcane fire
This is a little unrelated to the current discussion, but I'd like to post an interesting little scenario:
Abjurer 6/ Air Elemental Savant 10 / Archmage 5 w/Arcane Fire
for the purposes of this abstract experiment, lets assume his int bonus - his lost spells from high arcana produce something like the following chart.
NOTE: I KNOW IT'S NOT AN ACCURATE CHART, but for this hypothetical situation, it's good enough, and i'm lazy
total arcane fire damage:
spell level/#spells
0: 5
1: 5+3
2: 5+2
3: 5+2
4: 5+2
5: 5+2
6: 5+1
7: 5+1
8: 5+1
9: 4+1
Total Spells: 64
Total Spell Levels: 227
Now then, using every spell in his inventory to produce arcane fire, he does (64*5 + 227)*1d6 dmg = 547 total d6 of no-save, no resistance damage, with average damage being ~1,914.
The epic monsters known as "Devastation Vermin" would be completely helpless 1v1 this mage. The mage could just fly around out of range and blast the CR 39, 40, whatever Devastation Bug into pieces with arcane fire, because although the vermin have supremely high natural armor, a ranged touch easily hits them, barring a critical miss. Essentially, if the mage had 6-7 min. of uninterrupted time he could single-handedly kill a creature w/a CR much higher than his own.
Now, this is absurd. 6-7 min. is no time at all, and the mage could kill one of those things single-handedly? On the other hand, it'll never happen in a game (jinx), but I still find it amusing.
Overall though, I don't think Arcane Fire is unbalanced. I just want to know what others think about the fact that this is possible.
