Gems buy summons and, at a reported 50 Gems, a class change. Duplicates from summons are what ascension spends. Skill Crystals are the Update 3 currency for the per-unit skill tree. A skill-tree screen in October coverage says crystals come from quests, daily rewards and ranked wins. The code SKILLTREE pays 5 crystals, and GUILDFIX, LAESTRYGONIAN, UPDATE3 and MONGOLS also pay crystals on top of Gems.
Where Gems come from
- Codes. The seven October strings are the ones two October lists share. Their Gem side, ignoring crystals, is 5,000 + 1,000 + 1,000 + 1,000 + 700 + 700 = 9,400 if every one still redeems and you have not claimed it. SKILLTREE adds no Gems.
- The group, like and favorite bonus. Walkthroughs put this at 400 Gems once. Confirm the popup.
- Matches and quests. Score matters. One creator test put an AFK win in a normal match around 10 Gems. That is not the same thing as the Update 3 AFK Server, which is a separate passive mode and has no published rate here.
- The battle pass and ranked, after you are out of the tutorial.
Use the summon calculator with whatever price your banner shows. The 50 and 500 figures are the repeated public prices, including an October database that also says there is no ten-pull discount.
Rates that do not match
Do not treat any cell as official. Type the percent on your screen into the probability calculator if you want a count.
| Troop | Several September tables | One other guide | Seen on a summon screen |
|---|---|---|---|
| Spartan, Immortal | 0.19% | 0.08% | |
| Samurai, Berserker | 0.06% | Berserker read as 0.15% | |
| Crossbowman | 4% | ||
| Scout Rider | 20% | ||
| Laestrygonian | 0.01% during a Super Luck event |
An early September table also listed Gladiator, Centurion and Imperial Guard. Later rosters do not use those names, so they are not in the unit database. One October database adds a pity claim: 50 summons without a 3-star makes the next pull a 3-star, and says the featured three troops rotate about every 30 minutes. That pity rule is a single writeup. The banner text is the check.
What the Robux passes actually say
Prices below are the public product endpoint on 2026-10-10, before regional pricing.
| Pass | Robux | Official description |
|---|---|---|
| Skip Summon Spin | 79 | No description text. The name is the effect players report. |
| +50 Inventory Space | 99 | No description text. |
| Ascend All Troops | 199 | Ascends all eligible troops. |
| Pro | 1,499 | Pro tag in chat, higher guild capacity, custom guild emblem, 20 guild roles. |
None of the four pass descriptions changes summon odds. A September spending video describes a separate luck potion as tripling 4-star chance. That is a creator reading of an item, not a pass, and it is not a reason to buy the potion blind.
First-week order
Claim codes, claim the group bonus if it is offered, then summon the line you will actually evolve. A class change is 50 Gems once you know how you play. Switching every session competes with the duplicates you need. Inventory space matters only after duplicates are filling the bag. Pro matters if you run a guild, not if you want a stronger Spartan.
