i see like a lot of wr holders like doing a blip like jump out of the water but is there a specific way to do so

Only can be done on certain maps, specifically space where it's important. You have to jump off the slab at the start then land in between the blocks and the water at the bottom. Only works in 1.9+ I think. Takes some practice to get consistent though.

(in response to t8t0), space blip is indeed 1.9+, but certain blips like ravine blip are possible in all versions, including 1.8

Does this work if the ping is somewhere between 100 and 150?

aslong as the proper setup is done depending on which blip you are trying to do, its possible with any ping
