This is a simple guide how to defeat Lucien.
This guide will tell you the easiest way to defeat him and what the essentials are to defeating him.
Info about Lucien: Lucien is a high level boss and takes plenty of supplies and a good gear to kill, Lucien has different attack styles and I will talk more about those down below.
Since Lucien is one of the hardest bosses on the server you need plenty of supplies, I STRONGLY recommend using overloads since the overload potion restores your reduced stats from using saradomin brews.
You also need plenty of restores because in the late fight you are going to switch to dragon bolts (e) and you need to have your stats high at all times (more of that down below).
You want an Enhanced excalibur with you because this saves you supplies when you need to heal (mostly after drinking the overload potion).
Keeping spare titans with you is also strongly recommended since your titan is going to take lots of damage during the fight and might die (more of that down below).
Bring some steel of legends scrolls with you because this will help you speed up the fight even more (more of that down below.)
You want to bring the best gear you have, I'm currently wearing sirenic as body and legs which is T90 ranged gear with my dual chaotics. Lower end gear is fine as well, T70 gear work just fine. (Ignore my dragon boots because they are not range armor and I just don't have any range boots right now).
The important part is to bring with you lots of Ruby bolts (e) and Dragon bolts (e). Also having a full slayer helm increases your damage output by 15% if you're on a Lucien boss task which is great to have, but it's also fine with any other range helm.
Starting off the fight you want to pray ranged at ALL times since Luciens strongest attacks are ranged based.
Lucien does however have special attacks and a magic based attack.
When you start the kill you want to use your Ruby bolts (e). These bolts are HP % based and hit really hard in the early fight. They are capped at 2k damage.
When Lucien starts to get low health (below 3k health) you want to switch to your Dragon bolts (e). You can check his health at all times by rightclicking Lucien and click "examine".
You also want to start speccing Lucien at this point with your steel titan using the titans special attack "Steel of Legends". This speeds up the kill and because your stats might be reduced your Dragon bolts (e) wont hit as hard so the titan can help you out.
The titan helps out more than just speeding up the kill, there is a possibility that the titan will tank some of the incoming damages hence why you should bring a few titan pouches with you.
Id really recommend this method because Luciens most used special attack hits really hard.
This is one of Luciens special attcks, when he is waving with his staff and that black skull comes out of it, it means Lucien is going to do his Non-blockable special attack. This attack always damages you OR your titan with 500 damage, there is always a 10 second delay before he can use this attack again. This is also why it's really good to bring a titan with you since titans have a lot of HP and can help you tank many hits.
This is Luciens 2nd special attack, this is a ranged based attack and it's blockable with ranged pray, this attack hits even harder than the unblockable one so it's REALLY important to have ranged pray on. You may experience that you will stop attacking Lucien when he's doing this special attack, don't worry, you just have to click on attack again.
Lucien also got a healing ability, the amount he's healing varies.
Now after you've read this guide you probably should be a Lucien pro and after you kill him this message will pop-up! Congrats you have now killed Lucien!!
