Abaddon is known for his strong defensive abilities and supportive role in Dota 2. He can save allies with Aphotic Shield and Mist Coil, and his Curse of Avernus can provide valuable crowd control. His ultimate, Borrowed Time, makes him incredibly hard to kill and can turn the tide of battles in his team's favor. Here are his abilities: 1.Mist Coil: Abaddon releases a bolt of energy, damaging an enemy or healing an ally. This ability can also damage Abaddon himself, but it triggers his passive ability. 2.Aphotic Shield: Abaddon creates a protective shield that absorbs a set amount of damage and, when it expires, explodes to deal damage to nearby enemies. It can also dispel some debuffs. 3.Curse of Avernus: Abaddon's attack imbues the target with a slowing curse, while also granting a movement and attack speed boost to Abaddon and nearby allies. 4.Borrowed Time (Ultimate): When activated, Abaddon instantly dispels most negative status effects and any incoming damage he takes during the duration of this ability is converted into healing.

Alchemist can be played in different roles, depending on the team's needs. He can be a hard carry if given enough space to farm, thanks to his gold-generating abilities. Alternatively, he can also play a support role, using his abilities to control fights and provide auras for the team. Here are hi abilities: 1.Greevil's Greed (Q): This is Alchemist's signature ability. When activated, it provides bonus gold for each last hit on creeps and even more gold for killing heroes. Additionally, it offers a passive gold bonus that increases over time. This ability encourages Alchemist to farm aggressively and accumulate wealth faster than other heroes. 2.Acid Spray (W): Alchemist can release a spray of acid in an area, which deals damage over time to enemies and reduces their armor. This skill is useful for harassing opponents in lane and can also be used to farm creeps more efficiently. 3.Unstable Concoction (E): Alchemist brews a concoction that, when thrown, explodes upon impact, stunning and damaging enemies in the area. The longer he charges the concoction before throwing, the more damage and stun duration it inflicts. Proper timing and aim are crucial when using this ability. 4.Chemical Rage (R): Alchemist's ultimate ability transforms him into a monstrous melee fighter. It grants him increased attack speed, bonus health regeneration, and bonus movement speed. With Chemical Rage active, Alchemist becomes a formidable presence in team fights, and he can rapidly take down enemies with his high attack speed
