During the quest '002 The Secret of the Springs' when fighting Teleri I have no way to harm her. My attacks do 0 damage (God of War and wielding the Obsidian Blade) and the Poison Spell always misses. Is this a bug or am I missing something?

P.S: Prior to the quest, is there any way to change the scene with the ondins to something other than a gang rape?

Ahhh it's because the Obsidian Blade is an ice element, and Teleri is strong against ice. (The Poison spell also has a 50/50 and will be affected by the weapon you use, but I think I'll set it at next update to just hit 100% of the time instead. Ditto with being clearer on which weapons have what elements)

Choosing to go into the waters with them will always get this result (either ondins or naiads depending on your gender preference) so the only way to avoid it is choose not to go into the water
