How to fight trees?

[flavie]

I'd like to go to the Southern Lands of Mt Zulle, how to fight trees? They seem invincible..
Also there are trees to fight for the Dark Sun quest.
I've got Sandy and Akshbar.

P.S: I've bought 3 suits vs cold at Modern Sciences, it seems they don't prevent from fatigue, so I never use them..

[Indinera]

they prevent from coldness, though

fire powders work well against those trees

try fire attacks in general

[flavie]

Yes they prevent from coldness but there's still fatigue whether I use them or not.

We told me to use Oni and Metallic Curse, could I buy Fire powders now?

[Indinera]

yes, try to buy some, but i dont remember where there are some, sorry

it also depends on the level of your characters
