Introduction
Strongholds in Diablo 4 are more than just challenging side content. They are one of the most XP-rich solo activities in the game, especially around level 40 and beyond.

What Makes Strongholds Unique
Each Stronghold is packed with enemy mobs and capped with a mini-boss. Completing one not only grants major XP, but also unlocks new towns, dungeons, and waypoints.

Best Time to Clear Them
Wait until you hit around level 40 before tackling Strongholds. By this point, your build is usually stable enough to clear them efficiently, and the XP gains are worth the challenge.

Loot and Progression
Beyond XP, Strongholds offer gear upgrades, rare drops, and sometimes even side quests or world events. These stack up to boost your leveling efficiency indirectly as well.

Solo Strategy
Take your time with Strongholds—scout enemy groups, kite when necessary, and don’t be afraid to retreat. Use mobility skills and high AOE damage to control large groups.

Conclusion
For the solo player, Strongholds are gold mines of XP, gear, and content progression. Don’t skip them—plan to clear all available ones when you're strong enough to handle the challenge. You can learn more now from u4gm.com.
