Spellweaving makes me vulnerable?
This game is about consequences for your actions. Calling on that kind of power gives you a few vulnerabilities. When you click it on, you will be rooted in place. You cannot move, you cannot drink potions, and you cannot be disrupted. You are stuck. When you click it off, you are able to move immediately, but might be hit with a DoT and you will still have a debuff on you active. Every other stage you go through your resistance to physical attacks is reduced to -10% up to -30%. Your spells also cost more mana and even stamina during this process. When your stamina hits zero, you take on damage. A LOT of damage. And yes, you can die. A recent patch makes you immune to knockback.
