Compare

So I took some time to tweak an old character of mine of Exalted into an Infernal just to see the difference in power. The base character is probably about 2000 XP or slightly below (that's a lot). Infernals convert all this XP in bonus points (which are cheaper to spend then XP, ie using bonus point means probably 2-3 times, minimum, increase in total XP the character has).
Anywho we shall compare basic stats: original 5 Immac MA trees (all complete), new 5 Imacc MA trees, 1 Infernal tree, 5 DB charm trees (all complete).
Standard (unmodified) MA attack: org- 9 dice, new- 13 dice
Standard (unmodified) MA damage: org- 9 dice, new- 13 dice
Total Attributes (in terms of dots) org- 30, new- 46
Total Abilities (in terms of dots) org- 43, new- 98
Essence Pools (dots/total/personal/periphal): org- 5/52/14/38, new- 8/87/24/63
WP: org- 9, new- 10
Virtues (total dots): org- 15, new- 20

That about covers it. Wanna bet who wins in a fight between the two?
