I just uploaded a huge dragon overhaul!

This mod adds 15 new dragon types across the leveled lists and reunites my previous combat mods in one!. All the dragons have custom models made by me; expect to find dragons spitting sand, poison, electricity, infectious substance, acid, hot ash, radiant beams, magicka beams, lifedraining blood... And get ready to fight some really powerful elite dragons when you get to high levels! Their breath and melee attacks will be devastating. All the dragons have custom moels made by me! Be sure to check it out.
