When your in the item equip chest there will be different items "HELPFUL" to that level and "AVOIDABLE" for that level.
This could really come in handy for shadow lairs, noobs, bosses, or regular levels in general so we could all see what would help fend off those types of monsters.
or you could read the depth title and subtitle and use common sense to know what's there
(also the mission briefs and comlink missions tell you things too)
