For Ripping Warp, what damage increases with each 2 ranks? Obviously the +1 at base level does, but it's unclear if the d6, crit damage, Detonate Synergy damage, or Pierce damage are x3 at rank 6.
The ripping warp damage is 1d6 +1/ 2 ranks, so if you have 4 ranks it deals 1d6+2. With a Critical, you deal an additional +2 so using the same 4 ranks you would deal, with a Critical, 1d6+4 to Constitution and 1d6+4 to Charisma
If you have Warp rank 4 (detonate synergy), you increase the Ripping Warp damage by +1 (same example: 1d6+3 or 1d6+5 with a Crit). You increase it by an additional +1 if you have the Warp rank 6 Pierce. And having both gives you 1d6+3 from having 6 ranks +1 from Detonate Synergy +1 from Pierce and +2 if you score a Critical Hit.
All other effects that aren't included in the Ripping Warp description aren't unnaffected, so the Expose option of rank 5 still leaves a Mass Effect field and the Recharge Speed option of rank 6 still reduces cooldown (the Damage option of rank 4 has no impact on Ripping Warp because it increases the warp damage, which is replaced by the Ripping Warp).
