Venom

Ядовитый дракон

Assassin

Viper Strikeactive, magical damage

Venom spits deadly poison at the enemy with the highest attack power. The target takes 40 / 60 / 100 damage per second, loses 40% / 60% / 100% attack and movement speed and gains 10% / 20% / 40% Vulnerability. Duration 6 / 8 / 10 s, cooldown 6 / 5 / 4 s.

Role: a mid-priced ranged carry that also disables the enemy's main damage dealer, since the poison always picks the highest-attack unit on the board. Keep him in the back line; useful from the mid game onward and a natural fit for Dragon and Assassin synergies.

Synergies

Dragon · species

Synergy effect: (3) At the start of combat, 3 allied dragons have 100 mana (if there are more than 3 allied dragons on the board, the bonus goes to the dragons starting from the left side). (5) When combat begins, mana of all allies +100.

How to play

Dragon is a synergy about casting immediately: (3) gives three dragons full mana at the start of combat, so their skills go into the enemy right away, before any damage trade. The threshold is reached with mid-cost heroes in the mid game; place your dragons knowing the bonus is handed out from the left. (5) is a late build where the whole board gets starting mana, and it is especially strong with any heroes whose abilities decide the fight in the first seconds.

Assassin · class

Synergy effect: (3) Allied Assassins have a 20% chance to deal 300% damage with their basic attacks. (6) Allied Assassins have a 20% chance to deal 400% damage with their basic attacks. (9) After an allied Assassin kills a target, it gains one extra jump and its next attack is a guaranteed critical hit. Class trait: at the start of the battle, Assassins jump into the enemy back line and land a guaranteed critical hit with their first basic attack; the crit multiplier is taken from the highest active synergy tier. The effects of multiple synergy tiers stack: the critical chance is rolled for each tier, while the damage uses the highest multiplier.

How to play

Assassins are a back-line damage class: at the start of the battle they jump onto the enemy pieces in the back and land a guaranteed critical hit, and from (3) their regular attacks crit often. (6) raises the multiplier noticeably, and (9) grants extra jumps and guaranteed crits after every kill, turning Assassins into a chain-killing machine. The class is wide: cheap heroes let you reach (3) early, but the strongest Assassins are expensive, so (6) and especially (9) belong to the mid and late game. Assassins work best when someone else holds the front while they finish off vulnerable mages and archers.
