Telepath Tactics now supports terrain effects! You can dynamically modify any of the following based on what space a character is standing on: Strength, Psy Power, Psy Defense, Dodge, Accuracy, and any of the various resistances. (For the resistances, you can lay them each out individually--Pierce Res., Slash Res., Crush Res. Mental Res. etc.--or else affect them all at once just using the catch-all word Resistance.)
To set up a space to alter a character's stats while they stand on it, go into TileData and add a special attribute right after element for the tile you want to do this. For each stat to effect, use two values delimited by a comma: the stat name and the amount that gets added to the stat (this can be a negative value if you want it to be a penalty instead of a bonus). To affect multiple stats, delimit each with a forward slash. For example:
<Tile fileName="tile0001.png" passability="all" dmg="0" element="" special="Strength,-1/Dodge,10/Resistance,10"></Tile>
This will cause the space to give whatever character stands on it a 1 point Strength penalty, but +10 to Dodge and Resistance percentages across the board.
Also, unrelated: swimming characters now always have their Dodge reduced to 0 until they emerge onto land.
