Tales of Xillia

All I can recommend is that as soon as you can make use of link techs, do so; they are powerful and cannot be interrupted. When I first played I conserved the meter for bosses, but it charges VERY quickly, so just use it whenever you can.

Also, link yourself to beneficial partners whenever possible. Jude heals you when you get knocked down, Millia stuns enemies you stagger, and later members can break enemy guards, automatically block spells for you, steal for you, and drain hp/mp from enemies. These effects are generally valuable, especially the spell shield, since they occur without you needing to do anything.
