Arcon, you forgot to include the ws tp gain, its not 25/13. Assuming you ws with /sam and average store tp gear on a ws your looking at +25-30 store tp on a ws.
Your looking at 18.2 tp if all 4 htis land.
So 100- 18.2 = 81.8 tp needed until you can ws again.
81.8/4 = 20.45
20.45/13 = 1.573 , so roughly 58 store tp during tp phase.
carbonara + sam + SQ = 41, so 17 from gear
+1 Brutal Earring
+8 Ravager's Lorica +2
+5 Rajas Ring
+5 Goading Belt
Puts you at 19, and if you wanna equip it all you can adjust for misses on the WS.
Personally id go rr/vv/apoc, ditch SQ and just get the 38 from gear / regain
+4 Rose Strap
+1 Brutal Earring
+8 Ravager's Lorica +2
+4 Hoard Ring
+5 Rajas Ring
+5 Goading Belt
For 27 + 15 for sam, 6 for carbonara = 48
---> 13*1.48 =19.24 per hit
4 hits gives 76.96
4 hit ws gives 18.2 (95.16 tp)
And the last 5 tp you will get from regain in the time it takes to make 4 swings.
