I haven’t played on a normal official server, but from what I’ve seen, raiding is a bit expensive to do. The reward has to outweigh the risk to make a raid worth doing.
To make explosives you need demonblood and steelfire. For advanced tier players as well as experienced ones, this isn’t entirely hard to get. Explosives are enough to knock down a wall/door of the first tier.
However noob bases are likely to only have stone and a little bit of iron and wood available to raid. Hardly worth the costs needed to break into them.
A base that is built up, looking as if it has more crafting stations to process bulk materials is a bit more lucrative, but agian, in the noob area its likely to content a ton of iron bars at the most.
Tier 2 structures take about 4 explosives to get through per wall and are actually within the capability of a low tier player to construct. It just takes time. One could, with care and planning, make tier 2 structures incognito before ramping up productions. And thus be better protected.
Understand that at some point in time, you will be targeted for raiding. Its just a matter of when you seem to worth doing so. For different clans that will be at different stages of the game. Also understand that some clans may decide to preemptively strike. Driving you back protects them in the long run.
Its not always about wrecking a newbie’s day. Newbies in time aren’t newbies and can pose threats. Depends on the goals of those who are playing. Survival isn’t for the faint of heart. Expect to lose anything and everything at anytime.
But to thoroughly answer your last question. Is it hard? No. But raiding takes alot of prep work. Even a tier one base could prove to be a pain to raid. When i said it takes one explosive to tear down a wall. Its one wall. If you make an enclosed structure with multiple walls, it will take multiple explosives.
How you build a base could mean the difference between one explosive being needed, to 2, to 4 or even 8 or more. If you’re new, I doubt people will carry 80 weight of explosives to get a stack of 65 iron bars.
There’s so many things that can be done and counters to counters and a dozen methodologies to base building. Its just too much to much to list in one post. You’ll have to find what works for you.
