One of my players has a Cloack of Displacement, which grants, for every round, monsters have disadvantage attacks against the player until the first attack hits.
What follows from that power, is that I have to ask the player for every attack, if the monster has disadvantage or not. That is an extra effort I don’t want to do; the information about whether or not he has a benefit is on his side of the table. (Note: as a DM I always ask “does AC X hit you?”)
So, we want to change the Cloak; instead of granting the monster disadvantage on their attack, the Cloak offers him, for every round, a bonus to AC, until he is hit.
Here is my question; what bonus should the Cloak give to the player?
Assume the player is a level 12 PC with an AC of 16. If we need to take the attack bonus of the monsters into account; assume a master needs to roll a 10 to hit.
Description for Cloak of Displacement (emphasis mine):
While you wear this cloak, it projects an Illusion that makes you appear to be standing in a place near your actual location, causing any creature to have disadvantage on Attack rolls against you. If you take damage, the property ceases to function until the start of your next turn. This property is suppressed while you are Incapacitated, Restrained, or otherwise unable to move.
Does that mean the cloak makes your actual body unable to be seen and projects an illusion of your body nearby, or are both bodies visible?
“A car has a constant speed along a road. It goes down a hill at a constant acceleration. 50s after it goes down the hill the speed is doubled and 50s later it reaches the end of the 200m hill and is back at a constant speed. Find out the initial velocity and acceleration.”
At first I made relevant graphs to see if I could find some useful information from that but no luck. Then I tried to use the “suvat” equations but we haven’t learned them in class so I’m not allowed to use them, which is why I’m stuck as to how to solve this basic problem.
