In the "To The World Tree" demo (http://www.prankster.com/ttwt), I felt that the tactical combat didn't have as many options and choices as it should. Spellcasters had a lot of interesting spells to cast, but Fighters and Rogues were pretty limited. I've added some stuff which makes Fighters more interesting (the Powers system), and some stuff for Rogues (Singing Powers, mostly). Time to add something that will make both of them more interesting in combat.
So, I've added a Flanking system to combat. Attack someone, and you leave yourself open to augmented attacks from anyone else. Further, casting a spell or shooting a bow leaves you open to flank attacks from anyone. In this screenshot:
You can see Celeste shooting a bow from the back row, and getting a Flanking bonus on the Goblin Wimp because he is busy attacking TestNancy. Meanwhile, one of the Goblin Wimps is getting a Flanking bonus on TestNancy, since she's attacking the other goblin. (Look at the text messages at the bottom to see who is flanking who).
Flanking gives a 50% boost to attack success and damage. There is also an Improved Flank Skill which gives even greater bonuses; this is a proficient skill for Rogues, so it is a particularly interesting character build option for them. This 50% bonus (or greater with the Improved Flank Skill) is not a huge deal, but definitely could make the difference between victory or defeat in a closely matched fight.
The other big tactical combat change I want to put into effect is to make the different weapon types "interesting". Swords are accurate, Axes are less accurate but do more damage, and Staves are weaker offensively but give a defensive bonus. I'll work on that next.
