Looking for help working out some numbers.
I am developing a manual for bringing golems into the game (whether as loyal followers, dangerous enemies, or interesting NPCs). The main idea is that a golem, like any other being, can be assigned a Tier from 1 to 5. (I am also imagining zero-Tier golems that work like accessories -- more fun trinket than NPC.) I figure the main aspects of a given golem are its material, size, and complexity. So those is what players want to be deciding on with their golem.
Right now, I have material/size/complexity each graded on a scale from 0 to 5, with 0 being "trivially weak/tiny/simple" and 5 being "strong/huge/sophisticated." But I am having difficulty imagining how to translate these meaningfully into Tiers. For example, if Tier 5 represents the toughest creatures imaginable, would a gigantic mud mannequin (roughly a 0 for material, 5 for size, and 3 for complexity) be a 5? And if so, how should I grade the tier of a golem that's a 5 in all categories?
Basically, I'm trying to puzzle out a reasonable formula for translating my 0-5 scale for three separate values into Tiers. Any feedback is appreciated, because I've been going in circles with this for a while. Thanks in advance!
