Dunno if any of the anons talking about jewpri last thread still actively play it out of spite. For any that do, the jewel boards have actually become less cancer for f2p.
Chapter 47 adds high tier fragments, T3 scrolls and the T3 savior materials to auto battle drops.
Haven't had a scroll or the savior materials yet (you get like 60/day after depth 30 anyway) but fragments seem to be 20-22 of each every 24hrs, so about a week to get enough to unlock skill 2+3 upgrades and the skin, and about a month to get enough to unlock every node for a character. You'll still get fucked by character fragments (I've only had 4 Amethys...), but the 5* nodes are actually viable now.
You probably need to be around lvl 480 to beat chapter 46.
