The Toolbelt skill 
启用光子熔炉 has no cast time. Add it into the rotation when you are ready and use it off Cooldown.
Thanks to 
光能爆破, this build wants to 
过热 as quickly as possible. To achieve this, during downtime you want to Preheat. This is done by using 启用光子熔炉 and spamming Auto Attacks. 
全息震波 can also be used if immediate Breakbar damage will not be needed. Make sure to 
停止光子熔炉 around 80 Heat, erring on the side of deactivating a little early.
Before combat, make sure to face away from and do not target any enemies. 
水晶形态：风暴 gives Photon Forge Auto Attacks 600 range, so be careful.
One trait of note is 
太阳聚镜. With it there is a strong incentive to use the most damaging skills when entering, exiting, or overheating Photon Forge. The rotation already takes this into consideration, but avoid stray Auto Attacks getting the bonus damage instead of 
破片手雷 or 
光子闪击.
Rotation & Extras
Introduction
The unique mechanic of Holosmith adds a new Toolbelt skill, 启用光子熔炉, that behaves like a standard Kit, changing out your weapon skills for Photon Forge skills. This build uses these skills to quickly 过热 for a significant amount of Burning. The build has a very short ramp compared to most condition damage builds thanks more than half the damage coming from Burning.
As this build will use all three utility skills quite a bit, consider setting up custom keybinds for your 7, 8, and 9 skills. An MMO Mouse or adding Alt/Shift + 2/3/4 keybinds can greatly simplify the rotation. Experiment and find what works best for you.
Step One - Overheat
Before each combat, or between each phase, Preheat the Forge to about 80 Heat. See The Photon Forge sidebar for more guidance on this. When the encounter or phase begins, 启用光子熔炉 to quickly 过热 and continue with the rest of the loop to build up Heat to do it again!
- 启用光子熔炉 →
电晕爆炸 → 光子闪击 - Auto Attack until 过热
- 3x Kit Cycles
- 启用光子熔炉 → 电晕爆炸 → 光子闪击
- Fill with Auto Attacks
- 电晕爆炸 → 停止光子熔炉
- 1 x Kit Cycle, then Loop
For now, each Kit Cycle is to cast 
管流激增 and fill with Auto Attacks until you can cast it again. In the next few steps more skills will be added, culminating in very few Auto Attacks on Spear being used.
Step Two - Basic Kit Cycling
Every Engineer build draws its tempo from using at least one Kit. Condi Holosmith runs 3 Kits, which may feel daunting at a glance, but in reality is very simple and fluid.
Kit Cycle
This cycle is great practice since it only uses the 2 skill in each Kit. You will know you are cycling kits efficiently when there are about two Auto Attack chains on Spear before 管流激增 is off Cooldown.
Step Three - More Spear Skills
The first Spear skill used, 管流激增, applies a unique effect on the target: Focused. This allows your other Spear skills to have additional effects.
Whenever you use 管流激增 immediately use your 
闪电矛杖 skill afterwards. 闪电矛杖 is a flip skill that will start as 闪电矛杖 and then a few seconds later flip to 
电气炮轰.
The Cooldowns line up well so that 管流激增 can be cast after 闪电矛杖/电气炮轰 while performing other rotation steps, such as your Kit skills.
Additionally, cast 
毁天灭地 whenever it is available. This skill has an automatic follow-up attack on your Focused target, 聚焦毁天灭地. An easy way to use the skill is to use it after 闪电矛杖 or 电气炮轰.
Note, 
连绵起伏 is not used in the rotation for damage, but will provide decent Defiance Break to your Focused target.
Step Four - Advanced Kit Cycling
At this point, add in the other skills listed below for each Kit. These can be added to the rotation in any order, and at your own tempo so long as you fully complete the number of cycles to not delay 启用光子熔炉. Prioritize using these skills during the 3x Kit Cycles and not the single Kit Cycle.
The challenge of this step is making sure to not cancel any skills. See the Introduction to Engineer guide for additional guidance.
Step Five - Big Ol' Light Beam Barrage
The last three skills to add into the rotation are 
超级炸弹, 
手雷弹幕, and 
巅峰射线. Each of these skills add significant damage and should be worked into the rotation off Cooldown. An easy way to cast the first two is to replace Auto Attacks while in 启用光子熔炉 and waiting for 电晕爆炸 to come off Cooldown. You can also cast 巅峰射线 if over 50 Heat then, but it can also be used immediately after 过热.
Make sure to cast 巅峰射线 after 过热 in the opener! This skill is easy to cancel, so make sure to not move during the casting.
Transitioning to the Full Build
At this point, you are ready for the Full Build. As you keep practicing, aim to use all of your non-Kit skills as soon as they are available. For the Kit Cycles, get a better feel for the individual Cooldowns and slowly break from the rigid cycle. For example, you can drop a 
炸弹包 to 启用光子熔炉 faster or swap into 
手雷包 if you know 
冰冻手雷 or 
毒气手雷 will be available. Each Kit also has multiple other skills which have extra utility in encounters such as Defiance Damage. Comparing your logs to the bench's is a great way to highlight these opportunities.
