I personal find the Mage spells (like Firewall) have more power than playing a pure Ranger/Archer. But Explosive Arrows are also powerful!
But since I don't know nothing about the "fire resistances" of the different enemies, I don't know if Firewall (and other "Fire damage" related attacks like fire curse or Fireball ...)
is strong against ALL kind of enemies
OR Firewall is just more effective by a certain kind of enemies ???
In Divinty II you can see the % you're resist to Ranged, Melee and/or Magic attacks on your "statsitics" window.
So far I know Firewall is a skill of the Mage, so it is most effective by Rangers and Melee combat enemies?
If I'm right(?) you can follow the logical path that is:
Melee fighters are strong against melee attacks because of their Strength is higher, but weaker against ranged or magical attacks .
Rangers are stronger against ranged attacks because of their Dexerity is higher, but weaker etc....
Mages are stronger against magical attacks because of their Intelligence is higher, but weaker ... etc ...
But there're also enemies that have more than one kind of tacktical offense (and defense!), like Ambusias. Or Laiken, who make use of the summoning spell to summon melee fighters etc ... (if I remember right?)
It's up to you to find out more of the weakness(es) of enemies
