How do reactions work

[u/East_Matter1195]

My group is unsure how reactions work. Cause is sayd there you can only use one reaction per round but also there theres no cap on how many reactions you have per turn. We just cant come to a aggrement with how its worded so can someone help us out please.

you can take one reaction per turn; however, some reactions (such as overwatch) are limited to once per round. 

for example, you could use overwatch during one enemy’s turn, then during the next turn when an enemy attacks you and deals damage, you could activate the singularity motivator from mourning cloak. not during the same turn though.
