<p>I decided to write a new answer, because both of already existing are in my opinion quite unclear.</p><p>To get some <strong>Smoking Coal</strong> <img alt="" src="https://vignette.wikia.nocookie.net/tibia/images/7/7f/Smoking_Coal.gif/revision/latest?cb=20130903165737&path-prefix=en" style="height:32px; width:32px">first of all you need to meet<strong> Shlorg</strong> <img alt="" src="https://vignette.wikia.nocookie.net/tibia/images/2/28/Weakened_Shlorg.gif/revision/latest?cb=20130918170503&path-prefix=en" style="height:64px; width:64px">.</p><p>Aneg351 mentioned about Weakened Shlorg, but nope. You'll see just Shlorg - immortal stage.</p><p><img alt="" src="https://www.tibiaqa.com/?qa=blob&qa_blobid=11030025567841178916" style="height:481px; width:600px"></p><p>Just after you enter the spawn situation looks like on the screenshot. As you can see, there is no Smoking Coals.</p><p>So now you have to <strong>hit the boss in its immortal stage few times with SDs or deal noticable damage</strong> (I killed with avalanche/great fireball runes rest of monsters, hiting Shlorg at the same time and it wasn't enough). Thanks to this on the floor will appear Smoking Coals <img alt="" src="https://vignette.wikia.nocookie.net/tibia/images/7/7f/Smoking_Coal.gif/revision/latest?cb=20130903165737&path-prefix=en" style="height:32px; width:32px">. Unfortunately just a few on each stack (as I remember firstly it is max 3 per stack, but I might be wrong). Now you have to take one of the coal and burn up the basins, to change immortal stage of the boss into his weakened version.</p><p>And now, I have to add something very important in case if you want to collect Smoking Coals - <strong>the longer is your fight with a Weakened Shlorg, the more Smoking Coals appear on the floor</strong>. For example when I kill the boss I can take only 12 coals per fight. When long time ago a low level player killed the boss, I have found more than 70 coals. The difference is big, isn't it?</p><p>Okay, now I think it's nothing more to add.</p><p>Good luck!</p>
