If you thought that high level wizards are overpowered in BG2, think again.
Level 9 aloth can cast all the level 1 spells he wants in a fight and they replenish without rest for the next fight !
God mode activated - spam chill fog all around the map while not fighting, making that spell recharge yet leaving the AOE on ground.
Start a fight and keep spamming, blinding, chilling, doing bazillion amount of damage to an area.
Whoever said wizards are weak should repent ! the final judgment hasth cometh !
