Comment
All equipment is paired with Golden ShovelIn addition to the Big Show, nearly every piece of equipment with Gold Shovel cannot be stacked.
Curse Blade YesThe higher the number of stack searches, the higher the ratio of enemy minions (a separate 20% rate does not accrue proportion). Can reduce 2 stars at the same time if both items are activated.
Gold Shovel + Golden Shovel YesCreate Natural Armor and you can stack a lot to add "personnel" in the team.
Dragon Swipe YesThis equipment should be spread even more than the whole 2 Swipe the same general. Although 2 Swipe still stack higher than 100% magic resistance.
Hurry YesShould stack with 2 items, the stack will double the attack speed compared to 1 item.
Silent Mute Blade YesEach item has its own 50% silent rate and does not accrue 100% rate, so spread them out.
Heart Ice YesWhen stacked, it may not stack up 20% speeding effect but will stack armor, you can try about 5 Heart Range to watch.
Morello Devil Letter NoIt would be bad to have 3 Devils for a champion, because the effect doesn't increase x2 damage.
The Palace of LightIt will not activate double damage when there are two bows up and 1 champion. You should spread the equipment to the 2 generals to attack them.
Luden Voices NoShould spread to 2 generals instead of a general that uses up to 2 Luden Voices because 2 items still do not increase damage.
Ma Vu Song Kiem No You only need 1 Ma Vu for 1 champion, because 100% or 200% dodge it is no different. Red Charm NoJust like a Devil Letter, you only need 1 red amulet effect for 1 champion instead of 1 champion with two Red Charms.
Hat Witch Rabadon YesIncrease x2 the amount of AP received, if equipping Karthus with a 6 Magician's buff, there is nothing left to say.
Doctor Lien Thanh YesDoubling the attack range, almost 1 has included maps for the generals to have long arm, and increase 2 hit range for melee heroes.
Cheerful YesWith 2 or 3 items, it is possible to accumulate blows, increasing the number of targets that can hit up to 1-3-8 targets.
Atonement Chain YesThe recovery is double the amount of blood, but it will take a lot of material to stack up.
The Staff of the Great Angel YesDouble the amount of energy gained from intrinsic skills, equip Karthus and Miss Fortune.
Electric Knife Statikk YesVery hot when stacking a hero with 2 - 3 electric knives, it will increase 2-3 times the damage per activation. Suitable for fast speed heroes.
Ỷ Heavenly Sword YesLike the Silent Mute Knife, it only increases the ratio separately and does not increase the internal cracking rate of equipment when accumulated.
Swords ThereLike Dao Lang Lang and Ỷ Thien Kiem, it only increases by 25% a separate ratio to ban the opponent and does not accrue up to 50% or 75%.
Giap Gai YesIt's great to equip Braum 2 - 3, it will be 2 - 3 times the damage countered.
Blood Armor Warmog YesAdd up both blood and cumulative healing rate, causing the opponent to get tired of their hands.
The Great Ax of the Shell SoapShould equip the Gunners, the stack will increase the damage spread from the attack.
Stack up increases damage inflicted from the attack, very strong for Gunners
Phong Kiem YesIt is possible to stacks, but the rate of disappearing enemy heroes will be symmetrically positioned with the generals in your squad, so it is better to spread them to the 2 generals.
This is all the effects when stacking in TFT, based on this you can know when to stack the equipment for any champion when in the game.
