I started in Piscies a few days ago, and I figured that I should use my 2.5xp pot on Training island, so I can lvl quicker, but when I started fighting, there was no difference in exp? Do exp pots not work on training island or somethin? Thanks

I'm not sure, but from what he's saying, you should be getting the extra EXP, but there are other factors that aren't effected by it.

are you training on double exp day or regular days?

I trained on a normal day x.x

should work but it would explain why you see no diffrence. cause training island is just a regular island only plus about it is that they heal you.

originally when it fisrt came out people said it's an island where you get double exp all day everyday... but i wonder if that was really true. since igg likes to be idiot and take out stuff so we spend more not knowing. >.> when they can easily make money if it was a double exp always island. =.= wow they are so "smart" somtimes

So... it also depends on your base exp. ti gives 200 base. so lets say you get 250 while training there and you use a 3x potion you would only get 350 cause you are only raising the "50" above the 200. thats just a normal day.
on a double exp day the base is still 200 but the potion would give you 6x making its 500exp. so thats "300" above the base of 200.

if you wern't on ti then - the base exp is 0 so work it out from there.

200base and free heal each turn. thats just the benifit of ti, not really that great.. so if you ever get vouchers i suggest you save them for when you have pots and to only use on DOUBLE EXP ONLY (unless you have money to waste). 2x becomes 4x, 6x becomes 12x, 10 becomes 20. =.= isn't that better to wait?
