Erdengard Rules and Rulings

This is a collection of rules and rulings that have appeared during play in the Erdengard campaign, after consultation with Fry.

26th April 2020

Can multiple spells be cast during the same turn when one is cast as a bonus action?

We will ignore the following rule when quickened spell is used: Only a cantrip, according to rule:

[...] You can't cast another spell during the same turn, except for a cantrip with a casting time of 1 action.

— PHB p. 202

When using Quickened spell, you can cast a spell that has a cast time as an action using your Bonus Action. You ignore the limitation of being able to cast a single spell higher than a cantrip.

Update 14th June 2020: Fry has rescinded ruling, we are now going by the rules as written.

How do ranged attacks in melee work?

All ranged attacks have disadvantage:

When you make a ranged attack with a weapon, a spell, or some other means, you have disadvantage on the attack roll if you are within 5 feet of a hostile creature who can see you and who isn't incapacitated.

— PHB p. 195

Difference between spells that are cubes and spheres?

Because dnd is non-euclidian "sphere" is debatable in itself, but the big difference is that a sphere has the origin in its centre, while a cube has it on its face. See PHB p. 204-205.
Note that the origin of a cube may be included when casting a spell:

A cube's point of origin is not included in the cube's area of effect, unless you decide otherwise.
