Dampeer is the last HoN(Heroes of Newerth) Hero released by S2Games. They provided on their YouTube Channel a really nice Dampeer Hero Guide as a Hero Spotlight where you have basic knowledge of what Dampeer can do( for sure he can do a lot!) and how to play him.
In this Dampeer Hero Guide you will see what skills this hero has and the recommended item/skill builds to make. So if you wonder what items are good for Dampeer or how to play him, watch this video to have an idea.
If well played Dampeer is an OP hero. His Lifesteal abilities can turn a run for your life into a easy kill even if you are running on less them half life and you enemy is almost full life! The combination of Vampiric Flight (damage+lifesteal) and Terrorize(damage+"enemy running around") can really turn a gank around giving you a fast kill.
As stupid as this can sound, Dampeer is one of the few heroes(can only think of chipper to get massive farm on a huge/"staked" creep wave) where using you ultimate on creeps is actually a good thing to do. Doing it if you are farming for a bit is a really good idea since for every essence you get you are improving your skills.
Will make a full guide / tutorial when I have time and more knowledge about this hero.
If you have any improvements or tips just post them below on comment. Thanks
