kuja:

i would use my thunder magic on the bottoms of trees to make them fall over. id then burn the leaves and branches of some with flare and holy to make them logs. i would vary the sizes and gather logs and sticks as well as logs. i would burn holes in the top and bottom parts of the logs with some ultima,flare or holy. i would then make sure the holes are exactly the right size to slot other branches into them. this would link them together. when im riding my raft id use demi spells to use the gravity to make waves. id also cast demi in front of the raft to suck me towards the demi field but id always make it a safe distance away from me (similar to hanging a powerful magnet in front of a something metal to make it move.) this should make my raft faster than anyone else and linking my raft together would make it much more stable than leaves.

OOC: if you didnt understand parts of the plan just tell me.
