System Changes

The game is getting some major system updates that will affect how you earn rewards and how the early game plays out. Here are all the technical and gameplay adjustments coming your way:

Feats of Strength Update

• Feat of First Blood replaced with Feat of Warfare (triggers at 3 team kills)
• Aimed at reducing early-game frustration

Blue Essence and Account XP

Let’s talk about what’s probably most important to many of you – the Blue Essence changes. Riot admitted they made a mistake with BE calculations in their initial Season 2025 plans, and they’re making it right. You’ll now get 9,000 BE from Pass milestones instead of the previous 4,750 BE. For those of you who’ve already been grinding the current Pass, don’t worry – you’ll get a special one-time mission that gives you 4,250 BE to make up the difference.

The repeatable Epilogue milestones are also getting a massive boost, jumping from 50 BE to 750 BE per completion. Looking ahead to Act 2, they’re upgrading the final Champion Capsule to a Glorious Champion Capsule, giving you even better rewards.

Plus, leveling up your account will be about 40% faster now, which means you’ll hit level 30 and unlock ranked play more quickly than before.

This patch represents a significant step forward in balancing League of Legends for the 2025 season. The changes to Blue Essence and Account XP systems should make progression more rewarding for players, while the champion adjustments aim to create a more balanced competitive environment.

Keep an eye on these changes as they roll out, and make sure to adapt your strategies accordingly.
