gnarbrag: I think I spotted the problem.
Your crafter needs access to the spell(s). Having them memorized isn't required and having other chars with the spell doesn't help.
Darth__KEK: Malee seems to have
Ice Storm but not the ability to craft
Frost damage.
The character trying to craft is called Lady Carradine
kidalot: Yes I have temple Plus.
After much grinding for more gold and exp I was able to use the up/down arrows on the right to create a +2 weapon and I needed A LOT of gold to add Frost on top of that. So around 4,000 for just +2 and I think it was 15,000 with frost included. Not sure how much is needed for +3 or maybe I need to be higher level? Can't find any info on this.
I tested in combat and received a +2 on attack roll (chance to hit) and frost was added on damage roll.
I guess its laid out differently on temple plus or Co8 than vanilla game
Yes a lot of effects are greyed out because not having spell or caster level, if the effect is in red you require either more exp/gold but it doesn't say which until you have enough.
+1 2000 Gold
+2 8000 Gold
+3 18000 Gold
etc. (bonus^2 * 2000 Gold)
Frost counts as a +1 bonus so a +2 frost weapon costs 18000 Gold total. (plus the cost of the masterwork weapon)
---edit--- construction cost is half the value listed above in Gold + 1/25 of the cost listed above in XP
