As Beittil said the Charm of Energy dont seem quite right yet, as it is intended for casters the dex of it feels pretty silly and changing that to stamina instead would be a good thing..
current charm stats:
Charm of Energy: (caster version of 100k charm)
FT 3
ac: 12
dex, cha, agi = 9
wis/int = 12
hp = 100
mp = 200
+4 to all resists
Charm of Barrier (melee version of 100k)
ac: 20
dex,sta, agi, str, cha = 12
hp 175
mp 75
+ effect
Holy Charm of Protection (215k charm)
ft 4 + runes of healing
ac: 24
sta, cha = 20
wis/int = 24
hp: 160
mp: 190
+15 to all resists
and the 36k charms
ft 3
ac: 15
wis(or int for other charm) and stamina = 15
hp: 80
mp: 80
resists: +30 to one resist
So comparing charm of energy towards 36k charm currently gives less to the important stats for casters/healers and a total value of 39 (counting wis/int once) for the 100k charm vs 30 for the 36k charm.. however for the 36k charm all those 30 are useful, but in 100k case only cha, wis/int and to some extent agi is really useful.. the rest not much for casters...
4 to every resist = total of 20
so, basically switching up you lose
3 ac
10 points to resists
stats about even out...
and you gain
1ft (after the change to 36k charms)
20 hp
120 mp
-- I would want to see the resists for Charm of energy upped a little bit, ac upped to 15, and dexterity points changed to points in stamina
compared to the 215k charm, the 215 k charm should probably fall in line on mana ie change 190mp to 200 just as the 100k charm has, although 10 mana isnt really a super big issue.
