The Hamster King
OK, then I misunderstood. And indeed, having a single use for stacking is basically enough to make that part of the system work, if well balanced.
Pretty much how I see it as well. If there's a cost to spells, and stacking mana reduces that cost.... That's far better than a free spell, IMO.
The mana system could have some interesting side-effects if combined with some of the existing variables in the game. D'Tesh could sacrifice slaves for extra mana, Khazad could build a magical forge to convert excess mana to hammers, the Amurites could have a process availabel to them to convert hammers to mana, the Sheaim could pray to demons for extra power - essentially sacrificing culture for mana, the Elohim could earn bonus mana if their cities are healthy and happy, but lose mana if thier cities are unhealthy and unhappy.
Possible... Though the Khazad will have some use for mana.
So does this mean that a Tower of Mastery victory will become a bit harder as you'll now want some untapped mana to power your spells?
Also will there be any benefits to having multiples of the same manner, for example boosts to spell effects, cheaper mana costs, etc ?
Eh, not too much so. Up to you if you want Mana or if you want to build the Tower (still get mana, just not as much).
Already said we can have spell discounts.
Should be pretty easy to do.... Just an array of Resource + Discount amount, on spells.
