i'm aware simple is not the same as resourceless, i was just wondering if there were any other mechanics casters had claim on which didn't require tracking uses
honestly i wonder if you could try a simple caster as design variant on warlocks, give them unlimited pact casting but on a 1/3rd caster progression and only 1st level spells known (maybe limited access to a few higher ones through mystic arcarnum), no need to track slots and only having a small pool of spells to memorize all being cast at the same level.
Ah sure! Thats a good side discussion. What could we do in a sinole caster without ressources.
well "Cantrips" for me are "at will spells". So this can of course look different than 5e cantrips. It can be like the 13th ages auto scaling (like leveled spells) at will spells.
Of course you could also do something like taking normal spells, being able zo cast them an unlimited number of times but on a lower level, the only problem is that at low level like level 1 you would need to invent lower casting levels for these spells to work.
A simple spellcaster could also have "rituals". Which may be different than normal "at will spells" as they need to be cast outside combat and take a long while.
This could of course be non combat spells, but one could also do "armor of agathys" as a ritual or similar "limited buffs". Important here is that the number of rituals is limited else it becomes again complicated. (This could also include creating magical items, which only last a limited time (Wyrdwood wand the rpg allows that with some rituals))
another thing which could be used would be auras /aspects. Of which you only can have 1 active at a time. (This is something some simple 4e classes used).
5e paladin auras or 3.5 binder vestiges come to mind here. (Again not too many and not too complicated).
So like the 4e runepriest or the 4e vestige warlock. You have 2 states which give different aspects from which you can choose (and change from one into the other). Runepriest gave kind of an aura and vestiges warlock debuff on enemy you attack or selfbuff when an enemy dies.
Which of those 40 would you say was comparable to multitarget spells like web slow fog cloud firewall scorching ray &acid fog or single person ones like hold person ray of enfeeblement disintegrate? Don't forget teleport tiny hut alarm locate person/object/monster summon x & so on, can you dig up some examples of of those 40+ filling those roles?
Well magic does not necessarily mean that these exact spells need to be there. There are also less powerfull magic subsystems.
Also non combat spells like tiny hut can easily be rituals and with this in a different subsystem than spellcasting (like 4e did).
Also depending of the magic powerlevel the martial power level can be equal.
A legsweep can be a multi targeted attack (on a small scale) which can hinder enemy mobility (like web). On a bigger scale you could as a martial shatter the ground with your immense strength.
Hold person is literally just a grab. Or if you want a disabling effect: A punch to the solar plexus.
Debuffs could be holds which break arms or legs. (or just make them hurt a lot if its temporary).
So there is no reason to only make simple martials nor to make only complex casters.
