Let's say your main weapon attack is fireball which costs 10pts in char gen to make (including what casting type is it or is it sort innate ability you just have). If you want create 'more' fire spells, then I allow halve the cost of any later weapons added which total cost should not go past from original (so 10pts after halving down but full value being 20). If weapon is item, each weapon attack related to said specific weapon is 1/4 in cost (rounded down). Example of weapon is magic sword which main stats are weapon rank 5 (costing 10pts) but then it has some magic stuff in it (always needing pay 2.5pts for keep rank same with attack) which value cannot go past 10.
