Cannot Beat the Final Boss
Umbra is simply destroying too many of my towers to have any chance of winning. I ended wave 15 with 3700 gold, I had 4 fully upgraded archer towers aimed at the center and I'd filled every open holder with first level towers. After turning him into blobs twice, I was out of gold and only had two upgraded towers left, one of which I'd fully rebuilt more than once. Is there something I'm missing here or is this just a string of really bad luck?

I'm on normal and using Nivus if that helps.

Well what happend exactly? I recall I didn't spend all that much on upgrades but at least turned the archer towers back into Crossbow Forts - did you use a Rain of Fire on the boss at least once?

I spam cheap barracks on outside if he destroys them and then archer towers near him to replace what he took, if you use your meteor well he should die while ur cheap archers weaken him, if possible put down your helpers to block the blobs going back to the center.

If he starts destroying towers I would only build them up to level 2-3 depending which one it is as it be a waste of gold to rebuild them all fully

I tend to save my meteor for his blob stage and looking at both of your responses, that looks like a mistake. Maybe I'm leaving him alive too long during the second phase? I'll try this again when I get a chance and hopefully remember to take screenshots this time.

His blobs are harmless, best to save it to weaken him to the blobs state ASAP, also means he cannot destroy as many towers haha

1. You can make the boss fight with about 2000 gold, even on Veteran. (1500 if you want to push it even)
2. Go with your usual setup for the level, then when the boss fight starts, replace any destroyed Archer or Artillery towers that are in range of the middle road (where he teleports to the most) with Crossbow Forts UPGRADED with AT LEAST 1 level of Barrage (IMPORTANT), since barrage significantly boosts the amount of damage Crossbows do.
3. If he kills a magic tower, replace with an Archmage, or level 3 wizard
4. If he kills a baracks near your exit, replace with level 3 barracks (at least) or templars
5. If he kills a tower on the top edge of the level, ignore it or just replace with a cheap tower, he rarely goes there, his first teleport in every stage will always be to the middle road.
6. Fully occupy all holders on the level. Do not upgrade any tower too much, do not use Axethowers or DWAARPS at all as they require a lot of gold to work. If you think your setup is complete, then just spam low level archer or magic towers on the remaining holders.
7. Use Alric, Sha'tra, or Ashbite if you are still struggling. Nivus cant even survive a direct hit from Lord Malagar or Umbra's attacks, meaning that he will be dead most of the time.

How did you end up with just 4 maxed out towers and all the rest being tier 1 before the boss even spawned, @OP? Meteor Shower should definitely always land on him, not anything else (unless already there).

Here's Ironhide's guide if you're having troubles: https://www.youtube.com/watch?v=7HxehZ-ndgM

The first post was a bit unclear. I plenty had of fully upgraded towers, the 4 archer towers were just built solely to take out Umbra which is why I mentioned them. Based on the advice here, it seems like using Meteor Shower to take out Umbra's regular form as quickly as possible is what I need to do. Focusing on the blobs seems to be causing my downfall. Thank you for the tips and the guide!

Hahahha..

NEVER upgrade archer towers to full power.. it's a waste of money..

When he starts zapping your towers, you want to replace them with archer towers with 1 upgrade only, the 6 bolts.. and stop there..

Do not replace the towers which he zaps on the far left and right corners, only replace the middle and bottom ones..


He will usually go from top to bottom so leave ur artillary at the very bottom

Thanks to all of your great advice, I beat that shadow beast! It appears that Umbra's second phase is the most dangerous. So the sooner that phase is completed, the better off you are. It was 100% about dropping Meteor Shower on him. As promised, here are before and after Umbra screenshots: http://steamcommunity.com/sharedfiles/filedetails/?id=737053835 & http://steamcommunity.com/sharedfiles/filedetails/?id=737054190

I should also mention that Nivus wasn't killed once durning this level. I actually got the Caveman achievement along with You Shall Not Pass! and Great Defender. Thanks again!

I found a different setup that worked well for me (after failing several times). Having saved over 2000 gold before the boss fight (crucial), I built four mechas around the middle part and upgraded them with missiles. I placed all of them in the middle section.

- northern two spots before the throne
- the two spots below them were necro towers (1x pestilence and death rider)
- the two spots below these towers were the two other mechas
- a knights templar before each exit, with two assassin's guilds further north, one on each side
- the rest a mix of crossbow forts (with barrage) and archmage towers (one of them not at level 3)
(I made screenshots and I would post them if I knew how.)

I built the fourth mecha just after Umbra woke up for the first time. A few of them got destroyed but I just made sure that at least two or so were still functioning, and that there are barracks to help stem the flow of mobs.

Tip: If a fully upgraded tower gets destroyed, build it again, but don't fully upgrade it too soon - it's likely to be destroyed again, and then you've wasted a lot of gold.

I used Nivus since his ability to teleport in this map was massively helpful, even though Umbra one-shotted him a few times.

Obviously since Umbra is mostly in the middle and you need to kill him as quickly as possible, that's where your main firing power should be, so I guess archmage towers or the like will work similarly well.

My skill tree: 4x archery, 3x barracks, 5x magic, 5x artillery, 5x meteor, 0x mercs.

Exited with 2 stars although I think that with a few more skills, 3 would be entirely possible.

Hope this helps.
