Skill Spheres

Skill Spheres are artifacts that improve stats and passives. They have been removed since the Trials: Endgame Update, along with Passives, and replaced with Shards.

Description

Skill Spheres is a system which replaced the former Specs system. The Spheres can be attached onto characters to enhance their Defence and Hero stats, as well as abilities. The first Sphere can be acquired at level 5 and more Spheres can be used as the Hero levels further.

Slots and types

Slots

There are seven slots for Spheres in the 'Character' window. These slots are unlocked as you level up.

• Three Small slots unlocked at levels 10, 18 and 27.
• Two Medium slots unlocked at levels 15 and 30.
• A Large slot unlocked at level 40.
• An Uber slot unlocked at level 50.

Types

Every type of the Skill Spheres has its own specialty:

• Small Spheres increase stats and some minor Defense changes like range.
• Medium Spheres increase passives.
• Large Spheres give you a hero-specific bonus.
• Uber Spheres modify the way a certain skill or defense building works.
