Tricaru teams either succeeds or fail depending on whether every Icaru can survive the first wave of attacks and whether every Icaru can perform a Team Up. Many players care whether the runes look good on the screen, but the most important factor is whether the defense numbers will meet the requirements of the fight. There is often a gap between a rune build that seems promising and one that work, and this is due to the mathematics of the defense stats and which stats do not apply to every unit at the same time.
The defense of a second-awakened Icaru start at a fixed number. Every percent bonus to the defense of an Icaru will multiply the fixed defense number. Levels of the defense towers, guild bonuses, and the Determination sets all applies to the Icaru’s base defense stat before the individual rune defense stats are applied to the base defense of the Icaru.
How to use the defense calculator for your Tricaru team
Guard sets only benefit the monster wearing the Guard set. Determination sets benefit every Icaru on the team. When swapping pieces of equipment, one additional Determination set will benefit every Icaru at the same time, while one additional Guard set will only benefit a single Icaru.
The calculator will calculate these stats for you. The flat defense from artifacts will become important once all the percent defense bonuses are locked in. A few hundred flat defense points could complete a Tricaru build that is only a few percent short of the threshold for a successful fight.
However, flat defense points cannot compensate for the missing main stats on the Icaru slots two, four, and six. The defense bonus percentage stats are separated from the flat defense points on the screen for you to decide whether to hunt for another percent bonus or to hunt for flat defense stats. The calculator will also display the three Icaru units individually.
By displaying the three Icaru units individually on the screen, the calculator allows you to avoid the assumption that the strongest Icaru can carry the weakest Icaru through the defense checkpoint. Many players will spend time trying to find the perfect substats on every rune before they test the defense stats of they Tricaru team. They waste their time because one additional Determination set provides more defense to the team than several good substats on just one Icaru.
The same is true for the progress of the players defense tower. Completing the Guardstone tower will provide a flat percentage bonus to the entire accounts Tricaru defense stats. The payoff from the Guardstone tower will usually be more valuable than the substat of one Icaru.
The defense calculator will show you these stats, thus eliminating the need to have three separate spreadsheets to calculate your defense stats. The defense bonus from the guild applies to a narrow range of defense percentages. One percent bonus from the guild could mean the difference of whether you need one more artifact on your Tricaru team.
The guild bonus applies to the Icaru’s base defense before all other bonuses. Thus, this bonus will multiply with every other percentage-based bonus to the defense stats of the Icaru. Many players will ignore this bonus and focus on the runes.
However, ignoring the guild defense bonus will cause players to over-invest in rune decoration to compensate for the bonus that could easily be obtained from joining a different guild. All three Icaru must pass through the defense threshold at the same time. If one Icaru lands below the defense threshold while the other two Icaru units pass through the defense threshold, the cause of the problem is shared bonus.
Adding a Determination set to the Icaru or finishing the defense towers will fix the problem for the whole Tricaru team. If players focus on one Icarus substats, the other two Icaru will not be affected. The defense calculator will quick show you this.
Once you know which bonuses will increase the defense of your team, you can decide on your priorities for improving your Tricaru team. You will no longer focus on making every rune the same importance as the other runes. You will learn that some bonuses create more defense for your Icaru team than others.
This will allow you to create your own priorities for upgrading your Tricaru team.
