Caster Linking

[HamsterKun]

How would you link spellcasters together so as to have a total power greater than its components, similar to in Erfworld?

[Unoriginal]

Several casters can work together for rituals. Rituals can have effects beyond the scope of most spells.

Elaborate if you would

How about, two Spellcaster each uses a spell slot, and you can cast a spell that's a higher level than you normally would. The new spell level is the primary caster's spell slot level + half of the level of the secondary caster's spell slot, rounded up.

So if one 4th Level Spell slot and one 3nd level spell slot is expended, you can cast a known spell as if you had cast it with a 6th Level Spell slot.

You still can't know or prepare high level spells, so this is just for upcasting, so it has limited usefulness.

If you get a high level spell on a scroll, your DM might be able to figure something out to lower the DC, if multiple resources are used. DMs are usually more willing to fudge the rules if a limited resource is used in the process.

It’s actually an idea I got from Erfworld. My idea is that there’s a Psychomancer subclass for Wizards (Think of Erfworld’s Thinkamancer) that has create caster links as a class ability (maybe Lv10). Then, each caster in the link uses up a Spell Slot and the total spell level is equal to:

Average level of all Spell Slots consumed (rounded down) + number of casters in the link, including the Psychomancer

The Psychomancer would require a Lv5 Spell Slot to form a 2-caster link, and higher to let more in on the link.

Crafting? Glyph of warding combining multiple glyphs into a magic circle? It's a minimal homebrew.
