I'm not entirely sure what your question is.
what I mean is...what spell could be broken if given by itself to a non spell caster... so if given X spell (where X can be any 1 spell of your choice) Y number of times perday would it make the game harder to play... Y and X are both variables I am asking you to fill in. I gave some examples.
Movement and travel spells are usually a problem, in that the game expects the PCs not to have them at low level and to have them at high level. Teleport, Fly, Plane Shift, etc.
is it though? I mean yea it changes the game a bit...but it just takes the travel part and makes it easier.
lets try some examples:
1)Dr Strange sling rings... a group of PCs, lets say a Monk(Kensi), a Fighter (Battle master), and 2 Rogues (Assassin, and swashbuckler) at level 4ish find an ancient monastery and spend 2 years training with the ancient master who teaches them to use Sling Rings... At will they can misty step, they can spend a hit die to use the Arcane Portal spell as an action, and they can 1/short rest use the Teleport Circle spell... that would really just change how easy movement is...but would it break the game?
or even less breaking...
2) Portal Masters... a group of say a Barbarian 2 Fighters, and a rogue all at level 2 (so no sub classes yet) gain a spark of a soul shared between them...and they can as a shared resource plane shift 3/long rest... other then running away that doesn't really change much. It's too random of a teleport.
Unlimited access to Disintegrate or similar effects can be a problem, since the PCs can eliminate nearly all non-creature obstacles easily.
that's a good one, Disintegrate at will is a bit much... but what about 1/short rest?
Summoning and Polymorph effects can also cause problems if you have access to things significantly more powerful than you.
for the most part those spells are limited enough that if you get them even close to when a spell caster COULD have it would it?
High power healing or ressurection magic can make combat inconsequential.
this one is a good one, I often limit bringing the dead back...but I have seen games (High level ones) where those spells are thrown around without making combat inconsequential... heck in 3.5 I saw a Ranger/Cleric that prepped every spell of 5th+ as raises or higher and used them multi times... it was weird but it was 3.5 so there was a lot weird about that one.
Forcecage and Wall of Force can similarly warp nearly any encounter.
yea...save or suck spells...Hold person, tasha's laugh are both low level and spamable as is
could you elaborate?
Ditto this.
But the question is impossible to answer beyond that cuz of the Shroedinger's Checkbook issue.
Schroedinger's Checkbook
What a given effect or ability is worth is not measurable or determinable without opening the scenario box and looking at the situation and the needs of that situation.
I once saw a barapbarian hold a demon slaying arrow for 15 levels of a campaign and only use it in the final campaign ending battle scene after seeing the ultimate bad was indeed a demon. It was glorious and the value of that arrow immeasurable at that moment.
OK, so go into examples...good and bad that is half the fun of this type of thread...write some checks
