Augments were first introduced to Teamfight Tactics (TFT) through Set 6 Gizmos and Gadgets as the main mechanic. They became permanent in the game starting with TFT Set 8: Monsters Attack. Augments are basically permanent bonuses that are added to the player's hexcore. They are classified based on their rarity: Silver, Gold, and Prismatic. Notably, at stages 1-4, 3-3, and 4-6, players are offered three choices of Augments and rerolls.
The Final Reserves Augment is a Prismatic one offered in TFT Set 9 Runeterra Reforged. A lot of players consider this an OP (overpowered) augment in the game. Here's all you need to know about it.
What is the Prismatic Final Reserves Augment?
The Augment has a unique twist to it that comes in handy as a gamechanger towards the late game. The description reads, "The first time you would be eliminated or reduced to 1 Health, instead remain alive. After this effect triggers, at the beginning of your next planning phase gain 80 XP and 40 gold."
This will allow you to level up to Max level 9 and also field high-cost (5 gold) units. When your backs are up against the wall, this Final Reserves Augment can help you turn around the game.
Talking about how strong this Augment is, one Redditor posted, "So can we talk about the prismatic augment final reserve? When you drop to 1hp you basically get a free level 9 and another 25 gold. Combined with hedge fund it just seems too strong. When I hit level 9 I had almost 170 gold and was able to instantly hit my Senna 3 and win the game within 8 rounds. I think the 80xp it gives, is just too much."
