So I made a Teräs Käsi Master but I'm thinking it a little over powered... Any thoughts?

One thing that I always do is look at similar minis. Im not familiar with this guys so I can make an assumption on his power level but what you can do is take a look at miniatures from revenge of the sith. When I make force users I almost always use a different character as a base. Many of the Unique but non-key jedi from the saga are perfect base lines for example if you take a look at these two characters you can see the similarity to yours.Starting with stass you can see that her cost is a tad lower and so is her attack. She costs 22 and has 18 defence. Pretty generic jedi. Your guy costs 3 points more and has and extra +4 attack but a -3 defence. Pretty fair for a 3 point difference. But a 40 hp difference is about 5 points. She does have melee attack but not double or DR so that should add maybe 10ish points. Then were in the relm of agen kolar whos 32 (if your following my suggestions your guys cost is at 40ish about now. Agen is 32 and has almost the same stats but a little better his force powers though are fairly decent as a trade off for what your guys SA's are. So in my opinion you should raise his cost by about 10 points making it between 30-40. Hope this hellped.

Agen Kolar, Jedi Master

Force PowersForce 4
Force Burst (Force 2, replaces turn: 10 damage to all other characters within 6 squares)
Force Thrust (Force 1, replaces attacks: 6 squares; 20 damage; save 11 for 10 damage)
Recovery 20 (Force 1, replaces turn: Remove 20 damage from this character)

Looks ok to me, High Attack? well his defence is very low so not a problem as i see it.

At Home we use a cost total program to work out a point total, on our cost chart he comes out like this

STATS
Hit Point 100 = 11 points
Defence 15 = 3 points
Attack 12 = 8 points
Damage 20 = 3 points

Sub Total = 25 points

Special Abilities
Melee Attack = -5 points
Double Attack = 2 points (this is based on several factors such as attack/defence and Melee)
Stealth = 2 points
Teras kasi style= 2 points

sub total 6 -5 = 1 point

force powers
Force 1 = 1 point

Sub Total= 1

Total
Stats 25
SA's +1
FP's +1
Total = 27


So we would cost him at 27, so your 25 is to me fair because we cost stealth at 2 points, others might cost it at 3 and so on.

hope this is of some help to you.
