ToME: the Tales of Maj'Eyal

What is more feasible, big weapons and heavy armour or daggers and light armour? Note there is at least 1 skill tree that only works with light armour (mobility I think).

If I go anti-magic, are psiblades a feasible option to wok with this class?

Str, Dex, Con, Cun, Wis are all pre-requisites for important skill pathways. Some advice on this balancing act would be appreciated.

Thanks in advance.
