Yeah, I couldn't get by without this, and it's one of the main reasons I use the mouse a lot.
Some other useful tactics which especially help on Insane Mode:
Permanent Shield
Only fight when you have a damage shield on. If your shield has run out and is on cooldown then run away (preferably in a looping part of the level that you've already cleared) until it's off cooldown. Then activate it again and start fighting. This is essential fare for undead early in the game, but also an easy way to overcome many hard-hitting enemies for any character. Just beware of fast-moving creatures.
Hack 'n' Back
A version of the above for the shieldless. Only works if you're faster at movement than the enemy, but it can let you attack them without any fear of retribution. You also need some clear space to run around in. Also the enemy must be melee only, and preferably without any healing abilities...
Step one: Run away, and count on which turn you get an extra movement away from the critter. With 20% extra movement speed you should get an extra move every 5 turns.
Step two: Now continue running away with the enemy next to you, but whenever you would get your extra movement attack instead. Essentially you build up a buffer of extra action time that gets released in one turn, and the enemy misses out that turn. Repeat until enemy is dead. Works great against many bosses.
Note that you may not need a lot of extra space - you can just dance around a single tree until you'd get your extra attack (known as pillar dancing).
Ring-a-Rosie
A version of the above for ranged dudes, but you don't need extra speed to pull it off since the enemy pathfinding isn't always perfect. Find a loop in the level (around a group of trees or a small vault or a short tunnel) and keep running around it with the enemy chasing you. Whenever there's a sharp turn or a diagonal movement there's a chance the enemy will move oddly, taking a step in the wrong direction and making a space between you and it. Take the opportunity to shoot or ray the bugger and then carry on running.
A handy feature of all of the above is that the running away lets you restore your cooldowns, meaning each of your attacks will be a more effective stunning blow or pinning shot.
Unsymmetrical Advantage
Ranged goons can be a nuisance, but from some angles they just can't hit you. For instance it's common for meleers to wait behind a corner like this to prevent being shot at:
As soon as the skeletal archer comes around the corner you can hit it with a disabling attack and go to town on it without being turned into a pincushion.
There are also times you can target an enemy without it targeting you. For instance:
You can shoot the s, but he can't fire at you. A common tactic I employ against ranged bosses is to camp at one end of a corridor, shoot when they appear at the other end, then run away to the next junction:
Code: Select all
#.# #.# #.# #....#
#.######## #.######## #@######## #@####
#.@......# #.@......# #......U.# #.#
########.# ########U# ########.# #.######
#U# #.# #.# #......U
1. Wait 2. Fire! 3. Flee 4. Repeat
With the right layouts you can keep running around a certain structure, only shooting when the enemy is unable to target you back. Phase door rune can help if you slip up, of course.
