I’m playing in a D&D 5e Curse of Strahd campaign and we're strategizing about ways to deal with Strahd. Of the three important items we have to find, we have one so far: the Holy Symbol of Ravenkind. We're trying to strategize about how to use it most effectively.
Part of the text for the symbol reads:
Hold Vampires. As an action, you can expend 1 charge and present the holy symbol to make it flare with holy power. Vampires and vampire spawn within 30 feet of the holy symbol when it flares must make a DC 15 Wisdom saving throw. On a failed save, a target is paralyzed for 1 minute. It can repeat the saving throw at the end of each of its turns to end the effect on itself....
Sunlight. As an action, you can expend 5 charges while presenting the holy symbol to make it shed bright light in a 30-foot radius and dim light for an additional 30 feet. The light is sunlight and lasts for 10 minutes or until you end the effect (no action required).
One strategy we're considering involves using the Holy Symbol's Hold Vampires property and then (if Strahd fails the saving throw) using Sunlight while he's held to do damage.
The text for the symbol doesn't explicitly say that only one property can be in use at the same time, but that doesn't mean there isn't a rule about it somewhere that we just haven't seen, so I wanted to ask here. Is a strategy that involves having two effects of a magic item going simultaneously workable according to the rules of 5e? (This question and this question seem to be relevant but ultimately asking about different things.)
Note: I'd love any answers to be free of spoilers about CoS. Thanks so much.
