So the "new" trials for the lvl99 ultimate weapons are as follows:
20 Umbral Marrow (ADL) for Relic Weapons
10 Mulcibar's Scoria (PW) for Mythic Weapons
60 Riftdross/cinder (Ig-Alima/Botulus Rex) for Empyrean Weapons

Just a 'lil commentary: Why 20 ADL items and not kills SE? With the abundance of Relic weapons, the high manpower requirement for ADL and the single drop per kill you're encouraging the oldschool tiering of players that you tried to escape with the previous trials.
No need to answer. I know the reason is to bottleneck the 99 relics due to the ease of reaching 95. Just talking to myself.
