New Battlefield Effects
New battlefield effects are back on the Advanced Server. The Devs has made some optimizations based on feedback from the last test and added a new effect. The art performance for this gameplay is still under test and isn’t the final quality . The Devs will make the relevant gameplay available at a later time after this week’s patch update.
The Battlefield Effects tested in this patch are as follows:
- Nowhere to Hide: Pickable Crystals are available across the map. Upon picking one up, its energy circles around the hero for several seconds. If there are hidden enemy heroes within a large range, the energy will move to their location and grant vision of the area for several seconds. Optimized Crystal locations, making it easier for roaming heroes to pick up.
- Fire Turtle: Defeating the Turtle no longer grants a shield. Instead, an allied Turtle will spawn on the enemy’s weakest lane to help push it. Allied heroes near the allied Turtle will recover HP rapidly. Reduced allied Turtle’s HP but increased its HP Regen, making fights around the Turtle more competitive for both sides.
- New Effect – Golden Turret: Greatly increased the Gold shared to the entire team when any Turret is destroyed. Inner Turret and Base Turret HP are also increased. Increased the Gold granted by each Turret to every hero by 80. Increased Inner Turret and Base Turret HP by 1000.
