May 07 2025

In the Underground Castle 4 Knights and Broken Chronicles, players need to constantly defeat powerful enemies in the Catacomb and continue to pass the level down. Many players don’t know how to pass the 300th level. Here are some guides for passing the Catacombs and Broken Chronicles. Let’s take a look!

300-level guide to Catacombs

It's more sad to have no good equipment at this level.

Suggested pass-through values:

Master c Nana attacks more than 13,000

Address C Arcane 11000 or more

(Otherwise I can only bet on Helena's control all the time)

If your dual C attacks are both 1.5, then congratulations on it automatically.

Core conditions:

1. It's still a 30-round ring-able speed, with an attack speed of more than 18%.

2. Fiona must have a speed reduction guard, with an attack speed of more than 12%.

3. Elf cannot carry a ring that returns energy, otherwise it will be messy

Manual ideas:

In the first ten seconds of the game, Fiona will reduce the attack speed by 30%, and then a control cycle will be formed. The boss needs to use the ultimate move - Fiona interrupt. After three seconds, the boss must zoom in and hammer interrupt. After three seconds, the boss must zoom in and then Fiona interrupt (the elf can be restored). If this control cycle can be formed, then the survival pressure will be reduced next. Try to see the boss raise his hand several times.

When the boss reaches 1 minute and 15 seconds later, he will get two layers of stability, just put the hammer as he looks. Basically, you will have to be hit twice at this time, hoping that you will not be enchanted, and the enchantment will directly reduce the number of people. If you stick around here, the control will circulate above.

At this time 50 seconds, if your value meets the standard, then the boss will be violent. I hope your Fiona does not enter the persistent state. If you enter this state, you will not release your skills. If you can't control it, you will be stabbed in two seconds. Controlled good luck.
