In World of Warships , “rare bonuses” usually refers to the stronger economic bonus items that give bigger post-battle rewards than the common or special versions. The rare bonus tier shown in game/event coverage includes Level 3 bonuses such as Credits +160% , Ship XP +800% , Commander XP +800% , and Free XP +2,400%.

What they do

These bonuses boost how much progression currency or credits you earn from battles, so they’re mainly about faster grinding rather than combat power. A “rare” bonus is simply a higher-value version of the same type of bonus, not a separate gameplay mechanic.

How they compare

Bonus tier| Example effects
---|---
Special bonuses| Credits +40%, Ship XP +200%, Commander XP +200%, Free XP +600% 38
Rare bonuses| Credits +160%, Ship XP +800%, Commander XP +800%, Free XP +2,400% 38

Where they show up

Player coverage and community discussion indicate these rarer economic bonuses are harder to come by and often appear in special containers, seasonal rewards, dockyard/event rewards, or limited promotional drops. That’s why players often treat them as “valuable loot” rather than something you’ll use every match.

Quick Scoop

Rare bonuses are the high-end economic boosters in World of Warships: they don’t change ship balance, but they make your grind much more efficient.
