I recently got back into Dungeon Defenders after a bit of a hiatus in it. For those unfamiliar with it, it's a Tower Defense/Action RPG hybrid. Essentially you guard specific items (Eternia Crystals) from monsters that come in through specific doors and follow set paths. It's up to you and your teammates to set different towers, traps, auras, etc in their way to stop them. Then you can actually wade into the fray (or shoot from a distance if that's your thang) alongside your turrets and other contraptions. On top of that, enemies and chests drop items for you to equip and use. This can range from weapons to armor to vanity accessories. As you gain experience and level you apply stat points to your stats & skills to make yourself more powerful.
Each character has a different set of skills & towers/traps/etc, though there are some variants that share the same towers/etc.
The Squire's towers deal physical damage that is unresisted by enemies. The towers generally have higher hitpoints than those of other characters and are thus sturdier. The Squire also has two abilities to help him when he joins battle - a blood rage that makes him move faster and deal more damage, and a circular slice that is a small PBAoE for intense damage. The variant of the Squire is the Countess, a female knight that is faster but has less HP. She has the same towers as the Squire but her personal skills are "Joust", a rapid charge into enemies for high damage (and a high chance of flying off the edge of the map all too often) and a form of 'blood rage' that empowers nearby allies as well.
I could go down the list, but google yourself the wiki my fine friends
If you want to catch me playing it my SteamID is psychotideman, though I think my name shows up as Ade right now. Just lemme know who you are and that you're from CoH/Titan so I'll know and not be all weirded out and stuff.
