I need help on BBS!! (Ventus' Story)

I recomend tu level up XD I'm telling tu right now there's no way you'll be able to beat the final boss that if I remember correctly is the siguiente world.

But back on to helping, Mine Square can be made 4 ways:

Fira+Stop
Fira+Barrier
Aerora+Ignite
Stopra+Barrier

Captain Hook is only immune to the status effects mini, magnet and warp. So anything else works well so your on the right track with ignite and gravity.

If I recall I Think super glide makes the battle easier to dodge Hook, which tu can get in disney Town (In the area when tu come out on the roof from Pete's Pinball area, tu can use fuego surge and sliding dash to get across to it).

Hope the helps, if tu need más help I can buscar for my Stategy guide somwhere lol.
