In Lords Mobile the Altar grants temporary boosts to your army when you execute a captured leader. Upgrading your Altar increases the stats granted after an execution.
The Altar is usually the last building you unlock as it can only be built in the final area of your turf. It also requires a level 17 Prison to build, which can take a long time to get to due to the number of steel cuffs required.
Executing a leader grants a 24 hour boost to your troops. Executing additional leaders extends the boost timer further.
Your Altar provides an attack, defense, health and speed bonus to your troops. At level 25 this maxes out at 38% attack, 38% defense, 38% health and 21% travel speed.
As well as normal resources, your Altar requires Soul Crystals to upgrade. A Soul Crystal is found in chests, packs and purchased for gems. The majority will need to be purchased with gems, which makes it a very expensive building to upgrade. You need to obtain 20,000 in order to get to level 25.
The table below shows the resource cost, time and requirements for each upgrade level. You can find out your own build times by using our building calculator.
