In short, so far what I’m sure are:
1. Obtain keycard by defeating specific target champ (hint to be released per day)
2. Use that keycard to fight in Epic red room and obtain 258 intel per path completion (9030 Intel in total if complete all epic during the month)
3. Use that intel to exchange “Rift Detector”, or a bundle of “Rift Detector+Chorometer”, T4 Rift Detector cost 500 intel (limit to 18) and the bundle cost 3000 intel (limit to 1)
4. Enter and complete T4 Rift, player can obtain reward by chance based on the following chart:

5. If you use the chronometer, you can choose the path/reward by yourself
What I’m not sure are:
1. Whether the class AG are the same for everyone per day (I.e. all get the same class AG on particular day) or it’s random
2. Player who entered the Rift can “go out” and exchange the chronometer, then back to the Rift
Strategy (depends on unsure part)
1. Save 3500 intel first, then use 500 intel to enter T4 Rift and see whether the class AG you want are in the path (if AG class is the same for everyone each day then chronometer might be meaningless)
2. If you find the class AG you want, go out of Rift (not exit the Rift) and then buy the bundle and apply that chronometer to select the path you like.
Am I correct above? Anything to add? Thanks.
