This post is going to serve as a sort of definitive guide to the character classes in Telepath Tactics. I'll be updating this with info on the individual classes as the game progresses. Here are the classes, in all their pixelated glory:
SwordsmanA strong melee fighter with two counterattacks and the ability to "disarm" enemy counterattacks using Feint. She has a Double Strike attack that uses up all of her Energy in order to inflict double damage. She can use Shove to push enemies and certain destructible objects.
SpearmanA strong melee fighter with one counterattack and the ability to throw his spear. He has Impale, which can hit two enemies in a row at substantial cost to his Energy. He also has the ability to adopt a Defensive Stance, which gives him a 50% chance to block non-Mental attacks for one turn. Finally, he can use Shove to push enemies and certain destructible objects.
LizardmanA strong melee fighter with one counterattack, the lizardman is unarmored but has a 15% chance to dodge all non-Mental attacks. He moves quickly, covering up to 6 spaces per turn, and has a variety of special crushing attacks that can inflict status ailments like Slow and Weakness. However, as an ectotherm, he is weak against Heat and Cold attacks. He can use Shove to push enemies and certain destructible objects.
CavalryCavalry are strong melee fighters that ride giant mantises. Though they possess no counterattack, they can move a whopping 7 spaces per turn. What's more, they can move, attack, and then continue moving afterwards.
EngineerA weak fighter, he can build bridges and barricades to open and close routes across the battlefield. He can also lay explosive charges which, when detonated, deal massive damage to anything in their explosive radius.
AssassinA fairly weak fighter, but she gets a huge backstab bonus (and smaller sidestab bonus). What's more, she can move 9 spaces per turn, Leap over obstacles, and has a 20% chance to dodge all non-Mental attacks.
BowmanA strong attacker, the Bowman has a ranged counterattack and the longest range of any unit in the game. He can shoot an arrow and continue moving afterwards. He is frail, however, and can quickly be killed if not protected.
CrossbowmanSomewhat hardier than the Bowman, she has less range and no counterattack, but more staying power. She has a Bayonet attack for melee combat and an explosive Powder Bolt attack for detonating Charges and quickly destroying destructible objects.
PyrokineticistA middling fighter that attacks with Mind Blast. She has Heat psy attacks and can set enemies on fire, dealing continuous Heat damage until they die or are put out.
CryokineticistA middling fighter that attacks with Mind Blast. He has Cold psy attacks and can freeze enemies, preventing them from moving or acting until they thaw.
SkiakineticistA middling fighter that attacks with Mind Blast. He has Shadow psy attacks and can inflict Slow, reducing enemies' movement range.
PhotokineticistA middling fighter that attacks with Mind Blast. He has Light psy attacks and can inflict Blind, reducing enemies' chance to hit with non-Mental attacks.
Psy HealerShe has no offensive moves; instead, she heals with a variety of shields, and can create a movable battlefield obstacle with Solid State Shield.
MentalistA middling fighter that attacks with Mind Blast. She uses telekinesis to push and pull enemies and allies at a distance, which can be absolutely lethal on maps with major environmental hazards. She can also Levitate, gaining flying for a turn.
