League of Legends patch 12.22 official notes

1) The Return of Chemtech

Chemtech Drake

Chemtech Drake: When the Chemtech Drake is below half health, it gains 33% damage resistance and deals 50% more damage. This drake will deal 100% total AD + 4% of its target’s health as physical damage with each attack.
Chemtech Buff: When your team kills a Chemtech Drake, they will gain a stacking buff that grants 5% Tenacity and 5% Healing and Shielding power.
Chemtech Soul: Upon receiving the Chemtech Soul, players will receive a buff that gives them 10% damage resistance and 10% more damage while below 50% health.

Stim Fruits: Honeyfruits will upgrade into Stim Fruits and provide the usual heal plus a bonus shield in addition to no longer slowing champions that consume it.
Blast Cones: Blast Cones will now blast units within their range twice as far when they explode.
Firelight Bloom: Scryer’s Bloom will upgrade into Firelight’s Bloom, which will reveal a small area around the plant when broken, in addition to the usual cone in the opposite direction it was broken from. Allies tagged will also gain movement speed towards that direction for a short duration, and enemy wards revealed will be taken to 1 health.
