💡 Tips & Rules Reminders
Half & Third Casters: Round down each class level contribution individually before summing to find total caster level. Paladin 5 = 2, not 2.5.
Warlock stays separate: Warlock Pact Magic slots are NOT combined with the multiclass spell slot pool. They recharge on a short rest and always match the highest Pact slot level.
First level rule: Full casters need only 1 level to access the multiclass table. Half casters and Third casters need 1 level too, but contribute fewer caster levels.
Artificer (TCoE): Artificer counts as a half caster but rounds up instead of down when calculating multiclass caster level contribution. Level 1 Artificer = 1 caster level.
multiclass spells in D&D 5th Edition commonly seem truly powerful when one first finds them. Here the basic idea: if your player has more than one casting class, then one ties all levels according to a special rule. That rule sets the whole number of spell slot levels according to the table.
Here now the main rules. Full casting classes, bard, cleric, druid, wizard… Each level in them counts fully.
How Multiclass Spell Slots Work
For instance, imagine a player with three levels of wizard and two of cleric: one simply adds them to have five. For half casters, like paladin or ranger, one takes only the half of the levels and rounds down. For third casters, say, eldritch knight or arcane trickster, one uses only a third, also rounded down.
When one finished the above math, one looks at the table for multiclass casters from the Player’s Handbook. Here one finds exactly how many spell slot levels belong to every spell level. Funny thing: it is the same table that full casters use for their everyday spells, which truly simplifes the thing.
Here where everything becomes a bit weird. One can actually get spell slot levels higher than any spell your player truly can reach or prepare. Assume that you have five levels each in cleric, wizard, bard and sorcerer.
That results in a combined caster level of twenty, so you can use ninth level spells. The problem: each of those classes tops out at third level spells. Like this those ninth slots simply stay empty.
On the other hand, one can put lower spells in those high slots by means of upcasting.
In learning and setting up of spells, multiclass players handle every class on its own. For instance, cleric 2 / bard 5 only knows clerical spells according too those two levels. The number of prepared spells for every class stays its own; one does not mix nothing.
The player prepares the usual amount for every class separately. But after the spell slot levels are counted, one can cast any prepared spell from any class in them.
Here the good part: if you multiclass between two full casters, the growth of spell slot levels stays smooth. They follow what one expects. It becomes hard when one mixes half or third casters, because they add less to the amount.
For instance, cleric 2 and ranger 3 give a caster level of three, so four first spell slot levels and two second. You maybe do not know second spells yet, but those slots workfor upcasting.
Warlocks throw everything into confusion. Their spell slot levels come from pact magic, not from the usual casting. Levels of warlock do not enter in the multiclass formula.
Those slots follow their own way, but they can still back spells from your other classes.
