7.8 Balance / Madness SWTOR Guide

Vanquish will proc during the TK throw Spam Block and for the rest of your rotations it will be an instant cast.  Force in Balance is our DoT spread but is hard to time as it's fairly fixed in the rotation, making it difficult to time DoT spreads onto low Hp adds.

Force Armor is a pretty strong defensive on a very short cool down.  It is very useful in an op if you know a big burst hit is coming.  It absorbs 26k damage and reduces damage taken by 5%.  It is on the GCD, so using it is a DPS loss (as you are not using a damage dealing ability

Another Very short cool down solid Defensive Cool down, Cloud mind both lowers your threat, but more importantly provides you a 25% damage reduction.

This is our Self heal and is OFF the GCD, use it often as you take damage to help out the healers.  You can buff this with mysteries of the force at level 23, but you are giving up power of the force, making it a dps loss.  

This is perhaps the most powerful defensive in the game.  For 8" you are 100% invincible (note, some damage in the game will still kill you.  When the game wants you dead, you die.)  As it channels, you gain stacks of enduring bastion.  For every stack, you absorb 25k damage while the buff is active.  You become immune to interrupts for 5" after it ends, and you can use it as a C.C. Breaker.  Moving ends the channel.
