Trials

DetailValue
How to startTalk to Funny Valentine, or open the main menu and click Trials
Squad ruleWith 2+ players, form a squad first, then talk to Valentine
RewardsEXP and Cash — the main levelling route
Boosters2× EXP and Cash boosters work inside Trials
DropsWhen a Trial boss drops an item, everyone in the run gets it
GradingYou are graded on time and efficiency after the run; these feed your overall rank and rewards — but not the Cash payout

The efficiency grade is the part people miss: finishing fast without playing cleanly leaves points on the table. Clean mechanics plus a fast clear is what moves the grade.

Ranked 1v1

DetailValue
FormatOne versus one at the Colosseum
LivesTwo each — dying respawns you at full HP with no meter bar
RatingMMR, gained or lost per match
MatchmakingOpponent MMR and rank decide how much you gain or lose; the two players do not have to be close
Official adviceThe board itself says do not queue below level 100 because of the experience gap

Ranked pays rating rather than EXP, so treat it as a separate ladder from your levelling route.

Excavation

You wait inside the site for the timer, and the payout is a rarity roll.

CategoryDrop rates
SchematicsRare 22.75% · Epic 9.75% · Legendary 3.25%
Crafting componentsUncommon 15.66% · Rare 12.18% · Epic 5.22% · Legendary 1.74%
OutfitsRare 0.7% · Epic 0.3% · Legendary 0.1%

Wait time16 minutes — 8 minutes with Roblox Premium
How the roll worksIt rolls a category first, then a rarity, then a specific item
NoteSome categories have no entries at a given rarity, so the effective odds shift

Excavation is the cheapest schematic and component income in the game, and it is the only one that runs while you are not playing the combat loop.

Where these three fit together

TrialsEXP, cash, shared dropsYou need levels or the boss's drop
RankedMMR and rankYou are level 100+ and want the ladder

FAQ

Can I solo a Trial? Yes. The board says to play solo or with people; with two or more you must squad up first.

Do Trial drops get split between players? No — every player in the run receives the item that drops.

Is Excavation worth doing without Premium? Yes, it just takes 16 minutes instead of 8.

Does Ranked give EXP? No, it moves your MMR and rank.
