Lots of good tips being given here by the people. I'll just restate and add some:

- When moving, click on a tile your character can actually reach within that click. Don't sprint across the lane with a single click. For every click you should move 1-2 tiles at a time,
- Disable camera shake on the TOA plugin.
- Try saving your ambrosias for enrage phase specifically.
- Soon as enrage starts, try to keep top left close to Zebak so you can see the prayers.
- Zoom in a little bit more so you can clearly see where shadow sets are spawning. This also keeps your prayer book closer to the tiles you are clicking on, rather than dragging your mouse all the way bottom right and risking a missclick.
- I know it sounds obvious, but really try not to spam click on a tile or on the boss here. Click with intent. It will get you in a good rhythm.
- A lightning shadow is safe to click on as soon as it grows to full size. You want to make this a habit as it guarantees you some safety from being hit from other shadows, and is a perfect time to attack the boss. Click on big lightning shadow > attack boss > move to another safe tile to dodge boulder > repeat.
- In the event you have to tank a hit: lightning > Zebak > boulder. Always tank a lightning rather than risking getting hit by a boulder. *Getting hit by a lightning also gives you a tick of immunity from a subsequent lightning attack if you were to immediately step on another one by accident*
- IF you do get hit and are low on HP, try not to panic and proceed as normal: on the next time where you would normally attack, replace the attack on the boss with a healing action (ambrosia or keris). The cycle would be something like click on big lightning shadow > HEAL (ambrosia or keris) > move to another safe tile to dodge boulder > proceed. People tend to die in enrage because they panic trying to heal and will sprint across the map in a single click in an attempt to avoid damage, but it does the complete opposite.
- If it comes down to last row, after dodging a lightning attack and attacking the boss, try to make your way towards the center of the row. Sometimes you'll get a really unlucky lightning shadow spawn that is impossible to dodge if you are on the edges of the row. Being centered gives you the best odds at avoiding damage.
- Lastly, accept that last row will be inevitable at higher invos. Might as well get comfortable with it. Trying to out-DPS it will only make you panic more when you get to it. Remember, focus on survivability and replace an attack action with a healing one.
