What is Proof of Strength?
Stages with Specific Mutations

Similar to the Tower of Conquest (ToC) in Crossing Worlds, the Proof of Strength (PoS) is a collection of stages that have Stage Mutations
which modify the parameters of the enemies and characters present in the stage. Note that the mutations in PoS are 'fixed' allowing the player as much time as is needed to prepare for their next Stage.

Rank 1 Stage Guides

All stages in Rank 1 contain enemies whose levels range from Lv.31-40. Players who are max level can largely ignore the mutations and just auto-play each stage. Newer players will need to prepare both physical and magical attackers since Stages 1-5 have enemies with physical shields, while stages 6-10 have enemies with magical shields.

Proof of Strength Tips
Check the Strategies

An easy
way to clear Stages is by copying the party formations and strategies of other players. By clicking on the little book icon next to each stage, you can access the battle histories of players who have previously cleared the stage. Note that newly released stages will often have no strategies available since they haven't been cleared by anyone yet.
Adjust According to Stage Mutations

Since Stage Mutations in PoS are permanent, you can take your time when preparing the characters you think you need. Take note of each of these Stage Mutations and setup your party accordingly.
Character Enhancement and Upgrade PrioritiesRaise Your Voyager Level

Enemies inside PoS stages are level locked, so having characters that out-level them can largely reduce the stage's difficulty. If you aren't already at Voyager Level 60, you should definitely try to reach max level whenever you get stuck.

First Time Clear

Each of the Stages offer 1st Time
completion rewards ranging from Elysium Coins to Hope Luxites. If you aren't interested in the Profile Backgrounds, then you should at least play the game mode for the Luxites used for Summmons.
Proof Rewards

Proof Rewards are given out to players once they clear all of the Stages within a Rank. Included in the rewards are brand new Profile Backgrounds
which alter the appearance of your profile! So be sure to try clearing the highest Ranks!
