Obtainment: Defeat Shedletsky on the heights
In order to complete the mastery you must defeat shedletsky in an ultimate sword duel on the heights. To get to the heights you must first equip brickbattler and enter into the astral dimension, once you are there use the bomb to launch yourself into the sky of the astral dimension, you will find yourself on the heights where shedletsky is standing with the 7 sfoth swords, he will battle you to see if you are worthy enough to wield the sfoth swords. He will use attacks based on the sword he's holding, and he'll switch between swords. When he's at low health he'll switch to the illumina, once you defeat him he'll give you the sfoth swords and you'll unlock brickbattler mastery
When you use brick battler mastery you will have a selection to use all the sfoth swords, each one has it's own ability
Ice dagger - The ice dagger won't do anything at first but after 5 seconds of holding it, it will emit particles, once it does you can hit an opponent with the ice dagger and freeze them in a block of ice akin to the freeze ability's E attack, however downside is that the ice dagger has a smaller reach
Venomshank - the venomshank will have a larger hit box much like the firebrand, when you hit an opponent with it they will take a residual poison damage
Ghostwalker- the ghostwalker will deal less damage than the base linked sword however, when you kill a player you gain a temporary buff to your movement speed and sword damage, with the player becoming slightly opaque
Firebrand- Same as it was but now it isn't included with base brickbattler it will also give a burn effect
Windforce- It is a sword that when used will have 1.5x the knockback as usual
Darkheart- the darkheart has the ability that allows the player to heal from half the amount of damage done
Illumina- The illumina has an ability that when you lunge (double click when using the sword) you will dash forward allowing you to catch up to those pesky runners
