I think that in the second example you wanted to say yggdrasil seed, no?
well, the yggdrasil seed always heal the 50%, but if YOU want to change it to 100% change this:
608,Seed_Of_Yggdrasil,Yggdrasil Seed,0,5000,,300,,,,,0xFFFFFFFF,63,2,,,,,,{ percentheal 50,50; },{},{}
to this:
608,Seed_Of_Yggdrasil,Yggdrasil Seed,0,5000,,300,,,,,0xFFFFFFFF,63,2,,,,,,{ percentheal 100,100; },{},{}
