(These are the attributes I used)
12 Fire magic
8 (4+4) fast casting
12 (11+1) inspiration magic
6 (5+1) illusion magic
The skill set you shall use:
illusion of weakness
First off, cast illusion of weakness on yourself then put fevered dreams on the intended target then cast immolate and THEN smoldering embers. Once fevered dreams recharges you should switch targets the reason being since your target is taking damage from both your fire spells and burning they'll soon be dead and unable to transfer conditions. So the longer the enemies able to transfer conditions the more damage the whole enemy group will take. Use energy tap/ether feast and Ai + recast Illusion of weakness when needed.
+Possibly the biggest area of effect in the game
+Doesn't cause enemies to scamper
+Can take out a major group of monsters
+The sadistic satisfaction of toasty kraken spawn/outcasts/etc....
+Does a great amount of damage over a very large area
-The enemy can't be moving to be effected by smoldering embers but it can be switched out and replaced with another fire skill (like mark of rodgort(sp.)? ) or you could simply use a caster as a firestarter
Tidbits: burning causes 14 damage per second and immolation + smoldering embers burning durations last 6 seconds which is 84 damage to the target getting. But, Immolation and smoldering embers are cast constantly. So 3 combos will result in 84 x 3 =252 damage it's still not that great but it's over a VERY large area and unlike the rest of the fire skills it doesn't get reduced by armor (which i'm sure many monsters in the deep have a high level of. )
The enemy (The "fire starter") will have a damage rating of this: 184 damage (with 60 AL) and 3 combos would be (all though you should change targets) 183 x 3= 549 (put that in your pipe and SMOKE it )
Well that's all for now input is appreciated!
