Mirrorback spiders now work like RS3 - hitting one is always safe and passes half your hit on to Araxxor, up to 3,000. Only hitting Araxxor while one is alive bounces your damage back at you;
Hits Araxxor blocks while a mirrorback spider is alive no longer give combat XP or trigger Soul Split and other on-hit effects;
Familiars can no longer hurt Araxxor while a mirrorback spider is alive, and your familiar's hits - special moves included - never bounce back at you;
Araxxor's bounced-back damage no longer reaches players who have left the fight, died or logged out;
Corporeal Beast
Protect from Melee now blocks all of the melee hits and Protect from Magic blocks 33% of his magic hits, up from 25% for both;
Dark energy cores now only heal the Corporeal Beast by the damage they actually deal;
Drain ball now drains 1-4 Summoning levels instead of 10-49 and no longer drains anything when it deals no damage;
Skilling Production GUI
Production windows now have the amount built in - a slider, - and + buttons and a box you can type an amount into, right above the make button - no more chatbox step;
Production windows remember the amount you last made, or All, for the rest of your session;
Opening a production window now scrolls its list to the selected item;
Bone and herb burning at altars now burn the amount you choose;
Yakamaru
Fixed getting stuck in an endless choking animation after Yakamaru's strangling tendrils let you go - you're free to move and act straight away now;
Fixed being stuck in the pulling animation for up to 2 minutes after freeing someone from his quicksand;
Fixed the CPR animation carrying on after you stop resuscitating someone, and washed-up players now stay lying down while being resuscitated;
Fixed a sinking player who gets dragged ashore by Yakamaru staying stuck in the sinking pose on the shore;
The poison holder can now stand up to 2 tiles away from Yakamaru when his pool health runs out, up from 1;
His water vortex can no longer be passed onto washed-up players or the player being dragged ashore;
Sharknado fish now vanish when Yakamaru leaves the shark pool or its image is defeated, and no longer spawn a jellyfish afterwards;
Strangling tendrils now let you know with "A flailing tentacle grabs you by the throat!";
Fixed quicksand sometimes sinking a player where they couldn't be freed, or making a sealed pool's cover disappear;
Fixed Yakamaru skipping his weakened rise after dragging the poison holder under, and images of Yakamaru attacking without an animation right after dropping back into their pool;
Miscellaneous
You can now send a bug reports every minute instead of every 10 minutes, and have up to 10 unanswered reports instead of 5;
Archaeology collection names now show their numbers properly - Ii, Iii and Iv are now II, III and IV;
The drop viewer now lists drops you can't currently get - like the Wilderness loot table, brawling gloves and luck-only rolls - greyed out with what you need to unlock them;
Fixes
Distorted/Shadowy keys from Ancient caskets no longer send a news message to your friends;
Guildmaster Tony's mattock, Hazelmere's signet ring and Orlando Smith's hat now announce in red to all worlds, like Tavia's fishing rod;
Added the snowy 'Hunting Expert' NPC to the Rellekka snowy hunter area for the 'Hunting the Hunter' achievement diary;
Fixed Stealing Creation games that could show 'Game ending' and never end, leaving players stuck in the arena without rewards;
Fixed the furnace in Keldagrim doing nothing when clicked - you can smelt, deposit and withdraw there again;
Fixed the sink next to Keldagrim's furnace not filling your containers;
Fixed the Pothole in the Karamja jungle not letting you search your way into its dungeon, and climbing back out now puts you right beside it;
Using an empty container on the Herblore Habitat's cauldron now fills it;
You can now use flour on the Prifddinas well to make dough, just like any other water source;
Filling containers at the Underground Pass spring no longer also says 'Nothing interesting happens';
Wells, fountains, troughs and furnaces now only fill or smelt when you pick their Fill or Smelt option - climbing down a well or emptying a trough no longer starts filling instead;
Gorvek's right-click Transport option in the Croesus instance now works - it opens the corner teleports, just like talking to him;
Arianwyn in Prifddinas now sells the Trahaearn Exoskeleton set too, just like Arianwyn in Lletya.
