I have been building on a movement-skill miner using potions, indigon and bladefall of trarthus as a mana spender. In the beginning before the fight you see the mana engine coming to life, the mana potions will actually completely finish and the rest will be queued. This makes the playstyle a bit anoying but bearable.

A few important things to note

• It is very important to have enough mana left so that the bounce will never reach the top of your mana pool, if this happens the queue of potions will resolve leaving you with probably no potions at all since you will be spamming them.

• Frostblink mines of wintry blast do way more damage but do not trigger when there are no enemies in sight, this means that your mana reservation can easily be too much breaking your potion queue, so I prefer the lightning warp mines even though the mercenary prototype tech is a bit lame.

• The cooldown of your bladefall (30ms) determaines the hight of your mana oscilation. This is why I choose to be a saboteur so that I have 30 cdr out of the box, for 6 ticks you will need 51 cdr.

• This build has not yet reached the 16000 mana spend recently treshold, it is around 13500. Getting there means more mana open or lowering cooldown to server 6 ticks instead of 7 as shown here. You can increase the mana recovery with a transcended mind jewel or picking up the mind over matter impossible escape jewel so that you can access the small nodes for another 20% mana fron flask recovery. Another thing that I have been messing with is briskwrap but that chest is very bad in regards to defenses.

• I am using a divine flask instead of am eternal flask since it has higher mana per second recovery

• I am making good use of the "movement skills cost no mana" shaper mod to be able to throw my mines without any mana trouble

• "Non-instant Mana Recovery from Flasks is also Recovered as Life" from indigon is build enabling in this case since it gives me 3k life recovery
