This is probably infinitely more useful for Ready... Not sic.
Since say like... The new Rabbit Pet would be able to Foot Kick more often, since you have 3 Charges, and most of the time your Pet is sitting on 2-3 Charges While gaining TP, this will only allow you to burn them faster.
And thats a good Thing.
FK Sic, This i hot for Ready, and i'm entirely going to get it as soon as i can.
Aside from being easy to get and having Fantastic DoT, the Regain makes this piece simply extraordinary.
When engaged, it's like haveing StoreTP+30 on The pet (apprx 1.5tp/3sec), and that's before you factor in the fact that TP keeps building even when not engaged.
It's not really about boosting the damage of a single pet tp move. People tend to have charges left over in their tp building phase. So this just helps them burn them.
Drops off Bakka an Imp nm in Abyssea Konschtat. Killed this guy 4 times, First kill only Glyph Axe and 2 bakka wings. Second time 1 Goetia Chain and 1 Bakka Wing, Third time 1 Bakka wing and iolite. Then fourth time we got 1 Glyph axe + Goetia Chain and 2 Bakke wings. To kill him all it takes is 2 SMN's using Levi and BP spinning dive. and 4 BST to hold the NM with pets Makign an order to use the pets. Takes 12misn to kill Low man. Any melee is garenteed death. AoE Teir 4-Ga's + Damaging Tartans. It's very squishie.
Before you get excited about pet regain, keep in mind that Sic/Ready attacks at 100% are pretty much just as good as 300%. Impressive base damage, though.
