The Core Changes: Map Variants
MLBB Patch 1.9.99: Project NEXT adds four rotating map environments. Each one changes how you play, from ambushes to rotations and defense. They don’t stay permanently but cycle in, keeping matches unpredictable. Spotting the map type at the start is key as it helps you know which heroes and tactics will work best. So here is an overview of the maps:
- Dangerous Grass: Tall grass now covers spots like elevated areas, the central lane, and the Lord pit. Assassins and mages shine here since they can hide and burst enemies without being seen. If you’re playing gold lane, don’t overextend because gank risks are high. Stick close to your roamer for vision support.
- Broken Walls: Shattered walls create shortcuts across lanes and jungle paths. This gives mobile heroes an edge to steal objectives or sneak behind enemies. Tanks can also use these cracks to escape after diving. As a jungler, clear camps quickly so you can control these routes before the enemy does.
- Flying Cloud: A launch pad near your base lets respawning heroes hover for five seconds and fly over walls toward mid or enemy areas. It’s perfect for rejoining fights or stopping pushes, especially late game. Just be careful where you land and coordinate with your team so you don’t get caught alone.
- Expanding River: The river current speeds up, spilling into nearby areas and giving you movement boosts. This helps heroes without dashes move faster for ganks or escapes. Supports and tanks can rotate more efficiently, though the same flow makes slower heroes easy targets for ambushes.
New Hero Spotlight: Obsidia, Sovereign of the Abyss
Obsidia joins MLBB as a marksman built for the long game. She gets stronger the more she stacks her resources, making her deadly if you let her farm freely. Her mix of poke, mobility, and crowd control lets her dominate gold lane once she’s set up. You can unlock her for 32,000 BP or 599 Diamonds, and her first skin, Undying Remnants, is on sale for 51 Diamonds during the launch period.
Her skills in action are;
- Passive: Return to Bone: Every hit builds Bone Energy, with skills giving more stacks than basics. Once the bar fills, she creates a Bone Shard, and her next attack fires all shards at once for extra physical damage. The shards also carry effects from items, like lifesteal or slows. If you score a hero kill, you instantly get a bonus shard. This passive makes her a lane bully over time, so focus on poking with skills to ramp faster.
- Skill 1: Abyssal Bone Needle: This is her bread-and-butter poke. You throw a piercing needle that deals solid damage and builds energy if it hits a hero. Tap it for a single target or hold it to hit in a line. It’s cheap and spammable, letting you clear waves while stacking safely.
- Skill 2: Phantom Shadowmeld: Obsidia slips into shadow form with a burst of speed. You can use it to reposition, chase, or escape. It even reveals invisible enemies for a moment. During her ultimate, this skill gets better with a lower cooldown.
- Ultimate: Hunt of Bone: Obsidia throws her shards at a target, dealing heavy damage and tethering herself to them for 2.5 seconds. While tethered, they can’t dash or escape easily, and she can move through terrain while attacking. It’s powerful against backline carries but risky if you get caught in crowd control.
Hero Revamps: Abyss Theme Updates
Patch 1.9.99 doesn’t just introduce Obsidia as it also gives Alice, Dyrroth, and Thamuz a fresh coat of paint with reworked kits and visuals. These Abyss-origin heroes now feel more in tune with the current meta, shifting toward sustained pressure instead of raw bursts. Each one is also available with a 30% skin discount for the first week, except Alice’s base skin.
Alice – Queen of Blood
Alice looks sharper with her updated model and animations, but the real upgrade lies in her kit. She still relies on blood orbs, yet her passives now scale better in extended fights. Lifesteal feels stronger, and her area damage has more weight. She can be built tankier, making her flexible for both mid lane and roam roles.
Dyrroth – Corrupted Prince
Dyrroth’s revamp gives him a more demonic flair and a refined playstyle. His skills generate stacks quicker, letting him pump out damage faster. His ultimate now drags enemies in and slows them, giving you more control in fights. He’s scarier in the jungle or gold lane, especially on maps with broken walls where he can dive aggressively.
Thamuz – Lava Lord
Thamuz now burns brighter with a complete model redo and fiery new effects. His gameplay shifts toward constant wave pressure and ramping damage over time. He starts bulkier thanks to more base HP, but his immediate burst is toned down to push him toward team synergy instead of solo kills. Expanded river maps highlight his strengths since he can stick to targets more easily.
Roaming Role Enhancements
If you enjoy roaming, this MLBB Patch 1.9.99: Project NEXT patch gives you a lot more to work with. Roamers are no longer stuck behind on gold, and active play now pays off much better. You can impact fights and objectives without worrying about starving your build.
These are the things new in roamers:
- Equipment Changes: Roaming items like Dominance Ice and Radiant Armor have been updated. Their passives now boost your gold and experience gains by about 20 to 30 percent whenever you get assists, place wards, or help secure objectives. The new “Roaming Blessing” items even give small perks, such as a temporary shield when rotating.
- Passive Adjustments: Instead of being punished for not farming lanes, you now gain extra gold and experience from ganks, wards, and nearby kills. For example, placing a ward can give you 50 gold, and sticking close to allies in fights brings in scaled experience.
Events, Skins, and Rewards
Project NEXT also brings in several events, giving you plenty of chances to grab freebies and discounts while you explore the new patch.

System and Balance Tweaks
MLBB Patch 1.9.99: Project NEXT is not only about heroes and items. It also smooths out the overall experience. Controls feel more responsive with less input lag, and the UI has been cleaned up so you can swap builds quicker mid-game. Visuals look sharper too, especially particle effects on the revamped heroes. Items haven’t been overhauled, but you’ll notice subtle shifts pushing players toward hybrid builds.
Conclusion
And that is all for the MLBB Patch 1.9.99: Project NEXT update. What makes this update exciting is the mix of fresh features with the core gameplay you already know. It’s a good time to experiment with builds and heroes you wouldn’t normally pick. So, it is time to test.
