dnd 5e – When are the hardware components of Forbiddance consumed?

Spelling components are consumed only when they are explicitly indicated.

If you launch the ban every day for 30 days at the same place, the spell lasts until it is dispelled, and the the material components are consumed during the last casting.

bold = condition, italics = consequence

The wording is pretty clear – "If X, then Y and Z". X launches it daily at the same place for 30 days, making the spell permanent and the hardware components consumed.

If you do not put the ban on it for 30 days and you stop earlier, the components will not be consumed.

Of course, you can say that the sentence is ambiguous, but D & D 5th is not as logical as previous editions. He uses a regular English language and it would be foolish for the material components to be consumed before they become permanent. Otherwise, a single casting could be considered a 30-day progression, which means that the components would still be consumed.

dnd 5th – Can you cast the Elemental Conjure spell to summon an elemental in the Forbiddance spell's effect area?

the prohibition spell description states:

You create a protection against magical travels that protects up to 40,000 square feet of floor space at a height of 30 feet above the ground. For the duration, creatures can not teleport to the area or use portals […] enter the area. The spell also protects the area from planar movement and thus prevents creatures from accessing it through the astral, ethereal, Feywild, Shadowfell, or change of plane to spell.

In addition, the spell damages the creature types you choose when you cast it. Choose one or more of the following choices: celestial, elemental, fecund, demon, and undead. When a chosen creature enters the area of ​​the spell or begins its turn, the creature suffers 5d10 radiant or necrotic damage (your choice when you cast that spell).

When you cast this spell, you can designate a password. A creature that pronounces the password on entering does not suffer any damage with the spell.

The area of ​​the spell can not overlap prohibition to spell. If you cast this spell every day for 30 days at the same place, the spell lasts until it dissolves, and the hardware components are consumed in the last cast.
