My Homebrew Concepts

Blinkpop Blitzglitter rubs his gun just right, blasting a hot payload towards the shy troll.
Ryte whips his whip at the trolls juicy tree trunks "We're just getting started, let him watch, stay with us."

With that last shot the troll falls to the ground. Its covering now tatered to shreds and his large engorged member flops stiffly to his leg.

A question for everyone. I wanted to keep the OOC for the party discussion and this is a concept I have been thinking on some more lately.

Would a class that has you choose a archetype at lvl 1 and that archetype is what determined your second saving throw proficiency be too OP?
Example;

Start with INT choose an archetype;
Option1: DEX
Option2:CON
Option3:WIS

I don't think it would be OP at all. You're still only getting two saving throw proficiencies, right?

Correct. I was thinking getting an option would change the balance of a class. It is a support class were your archetype choice will determine how you support.
DEX: Party buff and field control
CON: Tank and taking attention away from others.
WIS: Enemy debuff and disabling.

As long as INT is your base save, you should be okay. Class saves generally include one really useful save and one not as useful. Since the three most-useful saves are DEX, CON, and WIS, pairing any of them with INT (the least-useful save) should be balanced. Although if this is a spellcaster, having INT and CON would be pretty sweet for those concentration saves, but I don't know how gamebreaking it would be.

Spells are part of it repertoire but it doesn't 'cast' spells, if that makes sense. It uses magic kinda like an artificer, kinda. That is closest class I can think of. It Imbues items for a one time release of arcane energy.
