Changes

To stop and ultimately kill a Altar Assassin, you must first defeat one of the Dark Realm Statue miniboss at the Altar to remove their invulnerability. As play commences on the first wave, the ground spawns will also intermittently produce Dark Prophets (an enlarged version of a [[Warboars|Warboar]], with light grey skin flair) on random lanes, but usually a different one each time cycling through the 4 ground lanes. A white exclamation mark will be shown above the area each will spawn from, but will vanish once it actually spawns, and no icon showing their location will exist after that apart from a regular enemy on the minimap. Once defeated, the Dark Prophets will drop a purple book on the ground. Be careful not to place or aim defenses too close to a spawn point so that when the Dark Prophets drops the book, it falls outside of the spawn point and you can reach it. When you collect the book by touching it, it will disappear and then show as a light grey debuff icon on your screen, and your hero will glow purple. Once you have a book debuff, give it to the altar by touching the coffin anywhere with your hero. The book debuff has no timer, but if you switch heroes or die, it will be lost. You can only hold one book debuff at a time. You must collect and bring 4 books to the altar to activate the summoning Ritual. There is no time limit for getting all 4 books, and they will remain there until all four are collected. The altar will display a message after each book is given successfully, and you can also see them placed on each corner of the coffin as you progress. The game will announce when the Ritual can be used to summon the Dark Realm Statue, which will be immediately after the 4th book is placed. Once the 4th book is placed, all other books currently on the map or in the possession of a hero will disappear, although more may spawn after this event as Dark Prophets continue to spawn. To activate the Ritual, you must interact with the coffin. When you do this, you will call forward a single Dark Realm Statue miniboss that is located in place of one of the 4 pillars, with the NE, NW, SW, SE pillars always activating in that order, with only one being summoned on each of the 4 waves. The Dark Realm Statue does not move from its location, but will attack you. The ritual only lasts 10 seconds. When the ritual is activated, the entire altar area is covered in a purple glow. If the Dark Realm Statue is not defeated during the ritual, it will vanish and any heroes inside the altar area will be killed instantly, no matter your defense or health level. You will then need to collect 4 more books to summon it once again. If you summon it again, the Dark Realm Statue will have the same remaining health as when it disappeared. When the Dark Realm Statue has been defeated, all of the Altar Assassins on the stage will lose their dark skin flair and they can then finally be damaged and killed. Each wave is over once all Altar Assassins on the map have been defeated. Defeated Dark Realm Statue pillars will be shown as broken in half afterwards. Once Wave 1 is over, repeat the whole process over again on each remaining wave. The incursion is won when all Altar Assassins on Wave 4 have been defeated.
