Replying to you Rowe. It only takes me two auto attack hits to get enough TP to use fullthrust or my other ws to start my combo (about 500 tp per hit). Also when you get higher level those first few cheap weaponskills will unlock a chain of higher combos if you meet the conditions. And when you use the following ws in a combo it won't require tp at all. Getting free weaponskills all the time
