Easiest way to get full potential TP is right b4 mob uses its TP up. Example: crab uses its TP up by using Metallic Body. After a few fights u kinda assume when they use up their TP, which if u cast Absorb-TP when u think they have about 90% u will get the most out of it which can be 50-75% or even higher. Pretty effective to use it right after a Guillotine. :p Darksday will obviously enhance it. Hope this helps anyone on DRK ^^
