After all that running around to get the grenades, I went out to test them - Ooof, is about all I can say. I'm pretty sure it's me not using em right, but you'd think tossing a grenade close to an enemy would take it out. The way I aim these things, I could take out every rocky area there is...my grenades seek rocks and cliffs but not undead whatever-they-may-be.
Any advice for grenade use would be appreciated...
