Here is some thoughts on Barb Diliente.
Sorcerer and Wizard seem both to go best with Barbarian diliante.
18 cha / 18 int both with 18 con.
I've made many with 8 in almost every other stat.
Enhancements, DDO potions, Ship buffs, +2 tome, rage and a +6 item would give either make a
34 con. - 340 hit points from con.
50 hit points from enhancements alone
23 from toughness.
160 from level.
20 from level one.
10 from Gianthold.
30 from GFL.
630+ hit points at level 20 on a caster, lol.
Other hit point boost can be achieved.
My bard with 18 cha/18 con should hit 670+.
He is a spell singer. Why does he need any onther stat? Many spell singers do songs almost continuely during raids, as well as buffs/heals. 23 ranks in concentration, 12 con mod, +8 enhancement to concent. +15 item and GH.
58 concentration checks (59 when rolling a one). I won't need quicken, possibly.
My cleric could have 710+ hit points.
Fighters could have 800+ with just one toughness feat.
All this with good looks, too!
