All Star Tower Defense X features a diverse roster of characters, each with variable damage, special abilities, and rarities. Magma Marine, based on Sakazuki Akainu from One Piece, is among the most formidable ones. The Unbound unit inflicts burn damage and possesses decent circle AoE attacks. It is exceptionally rare, yet several players are toiling to get the unit in their team.
Here's how you can get the powerful Magma Marine in All Star Tower Defense X.
Getting Magma Marine in All Star Tower Defense X

There are two ways to obtain Magma Marine in All Star Tower Defense X. Both of them require you to unlock and play Trial 2, which is a stage more difficult than those in the Story Mode.
The RNG method for getting Magma Marine is to complete Trial 2 repeatedly. The Unbound unit has a 1% drop chance in the Regular mode. Meanwhile, in the more difficult Strategist mode, it has a high 10% drop rate. The latter removes your units' Traits, Stats, and Hidden Potential, so you'll have to rely on strength and strategy to complete the challenge.
If you don't get the Akainu-inspired character as a Trial reward, simply purchase it from the Trial 2 Shop. Accumulate 250 Magma Coins, interact with the NPC managing the shop, and buy the Magma Marine Star Scroll. Next, open the inventory and use the scroll to receive the unit.
Magma Marine is ideal for all game modes. It can burn enemies with its normal attacks, while its special ability, Magma Meltdown, causes magma pools to appear on the map within the unit's range.
How to unlock Trial 2 in All Star Tower Defense X
Trials are unlocked in All Star Tower Defense X once you reach Level 25. It is a separate world that can be entered via its associated portal in the lobby.
While Trial 1 lets you obtain Etri, Trial 2 is a more difficult challenge that offers Magma Marine. To have the best chances of completing it, use units above Level 80 and add either Ziek (Beast Giant) or Airren (Titan Form) to your team.
Both Ziek and Airren have abilities that can destroy the regenerative shields of enemies in Trial 2. The Shielded enemies begin spawning from Wave 5 onwards and also appear during the last few Waves.
If you're planning to play on Strategist mode, there might be instances where you'll need to sell units and redeploy them to attack the durable boss.
