My hints for grinding the tower for koin and mastery levels.
Get a powerful damage talisman, WarHorn, Windbreaker, Chainsaw dude or a Meteor. Any of them will do basically the same thing once you forge it.
There seems to be Three Stores that have componants to buy. The Actual Middle messa has some things like +Projectiles. The Festiville has + Damge, +Recharge Speed, +Armor on Activation and. The thrid store is harder to find as you can not teleport to it. You need to walk to the final boss and take a left just before. It has a number of things there like +Gain health, +Time and +Elemental Armour.
Anyway I won;t go into how to buff evey talisman... but basically you need 4+ charges and 4+ Increased Recharge Time. You need +Damage and then either +projectiles or +time on screen...
but here is the trick and the point of the post.
Make sure you put in +Armour on Activation. You can buy these 7 at a time from the Festiville. It means when you press the button it will add armmour... beef this up... I think I put in like 50 or something.... anyway.. now when you activate the talisman at the start of the round your armourd and take no damage at all.. meaning you flawless every single match.
If you have it, also as soon as hey die start spamming the holiday fatality. This fatality is just hold block + UU. It can be done at any range. Far, close or medium distance. Even when the screen is full of things that would normally hit the opponent out of stun and make it so you can not do a fatality, just spam it and it will always go off.
So now as well as a auto win trinket you are assured of flawless and a fatality. This more than doubles the xp earned each fight.
Unless i missed something it does exactly the same thing. 1 meteor falls down + 1 meteor for each projectile listed.
I've built a talisman with it. I think it is a very diffrent effect. The Moonfall one is like a ton of arrows, this one is like gigantic rocks falling down.
