I'm working on a custom class and trying to come up with some novel things they might be able to do by writing magical glyphs and runes on objects.
I was thinking an interesting effect might be one that simply makes an object that a glyph is drawn on weigh an additional 50lbs. The limitations on the spell would be:
- Object must have at least 6 square inches of contiguous surface area (So doing it on chainmail, really small coins, or grains of sand would be impossible).
- No restrictions on whether or not the item is worn or carried. Could still be cast on an enemies shield, etc. This would allow for the enemy to make a dex save to prevent the effect.
- No weight restriction on the item it's cast on, doesn't matter if it's a piece of paper or an anvil.
- Has resource consumption via spell slots.
- Requires an action to cast, and has a range of Touch.
- Is granted by the class at 7th level.
- Should be roughly equivalent to a 3rd level spell in power.
- Lasts an hour. This might increase if upcast with a higher level slot.
- Only one active at a time - drawing this rune again causes the previous to disappear.
Now, the last one there might have some weird physics-puzzle implications, but that's fine by me.
Would a spell like this potentially break anything? I can't find any other weight-modifying spells that function similar to this, but if you are aware of one that is useful to compare, that would be great.
