Tips[edit] An early point in Greevil's Greed will significantly increase Alchemist's income. Smart opponents will make it difficult to land Unstable Concoction by juking and avoiding your vision, causing the backfire. It may be better to use it immediately when an enemy reaches the treeline, even if you lose damage and stun duration. Fully brewed, Unstable Concoction is one of the most potent stuns in the game, in both damage and stun duration. While the enemy cannot see your timer, they will still be able to see the "shaking" animation (Alchemist shaking his vials). It is imperative that you either start channeling within range, or channel a few seconds of the concoction from within fog before revealing yourself. This ability is most devastating to low armor support heroes who almost take its full damage upon impact, especially if they are softened up by acid spray. Use Acid Spray to dissuade enemies from defending their towers, or pushing into yours. Feel free to use Chemical Rage for its healing effects; it will even regenerate its own mana cost over the duration, and even more if you have%mp regen from items likeSage's MaskorPerseverance. Avoid skirmishes if your Chemical Rage is on cooldown, especially in the early/mid-game stage when you have few items. If you are in a tight spot and nowhere to run with low HP especially withoutTown Portal ScrollorBoots of Travel, use Unstable Concoction to commit suicide if possible. Chemical Rage is the strongest single target DPS booster in the game (giving a 70% boost in DPS at level 3). This means that Alchemist scales very strongly with right-click items, however at the same time Alchemist does very little damage without right-click items. This means if Alchemist is going to contribute into team battles down the road, it is imperative to get yourself some right-click. With Acid Spray it is possible for Alchemist to farm Ancients safely early on. This, combined with Greevil's Greed can (if used efficiently) give Alchemist incredible amounts of gold over time. It is not uncommon to haveRadianceorMjollnirby 14 minutes with this strategy. Beware! Heroes likeLifestealer,SlardarandDazzlecan remove the little armor you have, making you even more vulnerable and easy to kill. This is especially true in the case of Lifestealer, sinceFeasthelps him break you down. Though unlisted,Medallion of Courageis a very good item for Alchemist, helping add both armor and mana regen, as well as increasing damage dealt by attacks and spells as well. Build it in place ofRing of Basilius.Starting: Tangoesand aHealing Salve, along with aStout Shieldallow Alchemist to take a bit of damage while going for last hits. Iron Branchesare very cheap and give small attribute bonuses.Early-game: Boots of Speedgive a nice movement speed boost. Alchemist has relatively low starting armor, soRing of Basiliuswill give him a boost. Helm of Iron Willgives some armor and health regen. It builds intoArmlet of Mordiggian.Core: Phase Bootsgives a damage boost and the phase active works well with Chemical Rage's movement speed bonus to chase opponents. Armlet of Mordiggianis useful on Alchemist because Chemical Rage's health regeneration counters Armlet's health draining effect.Situational: Black King Barallows Alchemist to be uninterrupted in hit attacks. Radianceis a good pickup since Alchemist can get it very quickly with Greevil's Greed, when the burn damage hurts the most. Assault Cuirasslowers enemies' armor, which stacks with the armor reduction from Acid Spray. It also provides a useful aura to the rest of your team. Vladmir's Offeringprovides a useful aura and uses a Ring of Basilius as one of its components. Blade Mailforces enemies to think twice about fighting back against Alchemist. Mjollnirincreases Alchemist's attack speed greatly, and also gives a usefulStatic Chargeto protect Alchemist or his teammates. Abyssal Bladegoes well with Alchemist's high attack speed, and helps greatly in securing an enemy. It also gives a lot of bonus damage. Heaven's Halberdgives some Strength and evasion, and also gives the ability to disarm a threatening enemy. Heart of Tarrasquegives Alchemist a massive amount of health. Combined with the health regeneration from Chemical Rage, Alchemist is extremely hard to take down. Shadow Bladegrants Alchemist invisibility to brew up his Unstable Concoction. He can break the invisibility by attacking the enemy for additional bonus damage and at the same time launch his concoction.
